~ Bloons TD 6 description of Prince of Darkness

Prince of Darkness (sometimes shortened to POD or PoD) is the final upgrade in Path 3 of the Wizard Monkey in BTD6. It is the replacement for the Soulbind upgrade in Version 2.0. The Prince of Darkness upgrade allows the Wizard Monkey to summon undead MOABs and BFBs along with regular undead bloons, and the Wizard's personal graveyard capacity expands from 500 to 3000. In addition, all undead bloons, including his own undead bloons, will gain +1 damage and +50% duration lifespan, and only his undead bloons will be stored for up to 3 rounds instead of 2 rounds. Similar to the previous Necromancer upgrade, all its attacks gain +1 damage per 300 undead bloons stored, up to 10 times. The Prince of Darkness gains a massive range and attack speed buff in addition to the aforementioned benefits. Level 11+ Ezili will increase pierce of reanimated bloons by 50%, this buff is added before other buffs to pierce.

It costs $20,400 on Easy, $24,000 on Medium, $25,920 on Hard, and $28,800 on Impoppable.

General Description[]

Compared to its previous upgrade, the Prince has a greater range for its reanimation attacks, in addition to its capability to summon stronger undead bloons. The Prince also gains a buff to its main attack speed to four times faster than the base tower, which can help in taking down enough lesser bloons to summon undead MOAB-class Bloons. Shimmer also gains an attack speed buff to decamo bloons twice as fast.

In addition to its own extra benefits is a buff to all Necromancers, including himself. Each undead bloon gains +1 damage and +50% duration lifespan. Each Undead Bloon lasts for 15.0s instead of 10.0s.

Undead MOABs can deal 40 damage per hit and can deal damage to up to 20 bloons before reaching the pop limit or 30-second expiry (actually 20 seconds, but the +50% lifespan buff increases that value) but move at a similar speed to regular undead bloons. Undead MOABs consume 20 units from the Prince of Darkness's personal graveyard. This attack occurs every 3.0s, and only requires the personal graveyard to possess least 20 units before spawning.

Undead BFBs, on the other hand, move as fast as Undead MOABs but deal 100 damage per hit and can deal damage to up to 50 bloons before reaching the pop limit but last for a shorter time of 20 seconds (again, actually 13.3 seconds, but increased due to the same lifespan buff). Undead BFBs consume 100 units from the Prince of Darkness's personal graveyard, and it can only be spawned once the graveyard is at least 2000. This attack occurs every 3.0s, and it replaces the spawning of Undead MOABs.

Like Necromancers, Prince of Darkness stores popped bloons into a personal graveyard, local to each Prince of Darkness (if possible to have more than one Prince of Darkness like in Co-Op), and can store accumulated bloons popped for up to 3 rounds. Undead Bloons are spawned +20% faster for every 100 graveyard units, capped at 500 graveyard units, for up to +100% faster. All attacks gain +1 damage per 300 graveyard units stored, up to +10 damage. Each personal graveyard stores up to 3000 accumulated pops. Undead MOABs and Undead BFBs consume more pops from the graveyard than regular bloons, though.

Graveyard Units[]

See also: Undead Bloon

Accumulation[]

Prince of Darkness receives graveyard units by having bloons get popped within necromancy absorption range, measured as 70 range from the Prince of Darkness himself. Every single layer popped gives 1 graveyard unit. So one MOAB layer popped gives +1 graveyard unit, but popping an entire Rainbow Bloon gives +46 graveyard units, for example. However, from Rounds 81+ where Super Ceramics arrive, each Super Ceramic layer popped gains between 7-10 graveyard units by random deviation, top-and-bottom-inclusive, to compensate for the fewer children bloons per Super Ceramic.

If graveyard units reaches 3000, the maximum graveyard capacity for a Prince of Darkness, graveyard units stop growing until lowered again.

Depletion[]

Every time a Prince of Darkness summons Undead Bloons, it will consume a random amount of graveyard units from 1-10. Between 1-4 Undead Bloons will become summoned per send, each consuming the previously mentioned quantities of graveyard space. Each Undead Bloon receives a bonus amount of pierce equivalent to how much graveyard units were consumed when summoned.

Undead Blimps start spawning after achieving a certain amount of graveyard units. Undead MOABs require at least 20 units in the graveyard before these types can spawn, and consume 20 units each. Undead BFBs require at least 2000 units in his graveyard to start spawning, consume 100 pierce per Undead BFB, and will replace Undead MOABs until his graveyard count dips below 2000.

For every 100 graveyard units stored within a Prince of Darkness, he will deploy Undead Bloons +10% faster, up to 100% at 1000-3000 graveyard units. Damage of each spawned Undead Bloon increases by +1 for every 200 graveyard units, capped at +10 at the maximum 3000 graveyard units, stored within a Prince of Darkness prior to spawning the Undead Bloon, but does not affect the rate of consuming graveyard units. Rate of spawning also applies for Undead Blimps, but bonus damage for Undead Blimps only applies for Undead MOABs.

Graveyard units stored in a Prince of Darkness last for up to 3 rounds before being automatically depleted.

Strategy[]

Summary[]

With the massive Version 21.0 buffs to Prince of Darkness, it is an extremely powerful cleanup tower, and actively acts as a guard against the exit. With the nature of super powerful Undead MOABs and Undead BFBs, they can demolish groups of weaker bloons with ease, especially normal MOABs and Super Ceramics in late-game. Not only that, it comes with a greatly improved Shimmer attack, useful for countering the camo properties of DDTs. It becomes extremely powerful with sufficient supporting DPS towers nearby, but without sufficient supporting DPS towers it becomes extremely weak.

Prince of Darkness comes with massive range plus massive enhancements to all its attacks: 4x faster bolts, 2x faster shimmers, and +1 damage and +50% lifespan for all undead bloons on screen. The scaling attack speed and damage of all undead bloons becomes even more significant on the Prince of Darkness, for up to +10 damage and +100% faster, alongside up to +10 pierce like all other Necromancers. At maximum strength, the powerful army of undead bloons paired with undead BFBs can obliterate large groups of bloons below ZOMG with almost no trouble, even versus BFBs.

Tips[]

  • The Prince of Darkness, although super powerful at its maximum power, requires some support in order to become effective on rounds where single-target damage per second is important, especially rounds like round 80, 85, 87, 97, and 100. Adding towers that are effective countermeasures against high-HP singular blimps, such as Maim MOAB or Spike Storm, are helpful.
    • Prince of Darkness can also get overwhelmed with too many ceramic bloons at once, meaning support is recommended for it to beat rounds like round 98.
  • When used in combination with general supporting damage to build up its undead bloon count, Prince of Darkness can fully solo the DDTs on rounds 90, 93, and 95, as well as almost completely solo the Fortified DDTs on Round 99.
  • Letting the majority of the main defense attack close to the Prince of Darkness is helpful so that the Prince of Darkness can generate graveyard count a lot more reliably. Since the Prince of Darkness's actual graveyard collection range is smaller than his massive base range, 70 range instead of 80, it is important to add supporting towers nearby him for assistance.
  • Use 2-0-5 Prince of Darkness on maps with Line of Sight issues, like Flooded Valley, but use the 0-2-5 Prince of Darkness to utilize the potentially extremely high damage output that it can deal. Note that Wall of Fire will always target the closest area of track, which means the massive range of Prince of Darkness does not affect the Wall of Fire attack's positions whatsoever.
  • Just like Necromancer: Unpopped Army, the Prince of Darkness is best used on single-lane maps, although because of the new Version 21.0 buffs it will always spawn from the exits and aim towards paths where bloons are closest towards the exit.
  • Prince of Darkness, like Necromancer: Unpopped Army, is best used for anti-stalling and is optimized with anti-stalling. If used purely for anti-stalling purposes, place near the start of the map alongside extra MOAB-class damage support. This will allow the Prince of Darkness to easily gain maximum graveyard capacity to summon many powerful Undead MOABs and Undead BFBs, for maximum damage output. Otherwise, placing within close range of any exit(s) to optimize its cleanup potential in CHIMPS games.
  • Compared to the Necromancer: Unpopped Army, the Prince of Darkness is an excellent choice as a general cleanup tower for beating late-game Super Ceramics and general MOAB damage. Provided it is supported by nearby backup defense, the Prince of Darkness is capable of dishing out massive damage overall.
  • Placing Necromancers nearby a Prince of Darkness can actually compete for the same pop, meaning that they can actually steal Prince of Darkness pops. However, having nearby Necromancers isn't always a bad idea because this can make all of them pack a bigger chain reaction against dense bloons.

Version History[]

Replacing the old Soulbind upgrade, Prince of Darkness's role is to improve the undead bloon attacks. However, it was initially very weak outside of exploiting a Sandbox Mode bug that was later patched out. One major rework in Version 18.0 increased its overall reliability, but not nearly enough to make it useful outside of custom challenges. However, the Version 21.0 balance changes has extremely improved Prince of Darkness's power to the extent that it become an extremely cost-effective mid-to-late-game Tier 5 tower.

Version 21.0 has overhauled the power of the Prince of Darkness by adding a significant damage-scaling mechanic to all its attacks, alongside a few quality-of-life changes that improve its reliability as a higher-scale cleanup tower in the late-game. The damage scaling was toned down in Version 23.0, but nonetheless has made its way as a very popular CHIMPS tower for not only its incredibly powerful cleanup role but also for reliable decamo. Version 28.0 nerfed Prince of Darkness's pop accumulation of Super Ceramics by lowering the upper boundary of graveyard units gathered per popped Super Ceramic.

21.0
Though it was never a goal for the base tower to be great, given the additional purple weakness since BTD5 and how poorly it currently performs we feel it deserves to take rank as the cheapest magic tower along with a small buff. [...] Finally, Unpopped Army changes are also here! We wanted to cover all of the usability issues with this upgrade while also powering it up and expanding more on the mechanic that makes it so unique. We hope this will be enough to make Wizard very useful in a number of ways, but will be keeping a watchful eye on how it plays out.
~ Ninja Kiwi, referring to base Wizard and Necromancers
  • Buff Undead Bloon attacks now gains a bonus to graveyard after round 81 to make up for the total decrease in child Bloons that are created from Super Ceramics (about 10 per pop).
  • Buff Undead Bloon attack targeting has been reworked to function in a smarter way, summoning Zombie Bloons further back to avoid them spawning behind Bloons, and also on multi-lane tracks targeting the lanes that are likely to leak sooner.
  • Buff Necromancer (and by extension Prince of Darkness) now enhances the power of all of its attacks by 1 for every 200 souls in its Graveyard. This can stack up to 10 times for Prince of Darkness.
  • Buff xx5 Prince of Darkness max Graveyard capacity increased from 2000 → 3000.
  • Buff Main bolt has more pierce (7 → 8, inherited from the base Wizard pierce buff).
23.0
[...] We've also added some previously intended minor changes to Prince of Darkness which were held back due to bugs that have now been resolved.
~ Ninja Kiwi
  • Buff Prince of Darkness pops retained in graveyard increased (2 → 3).
  • Nerf Prince of Darkness grave required for damage stacks increased (200 → 300).
25.0 (Possibly? 27.3 discovered)
  • Buff [undocumented] 1-0-3 Shimmer now activates over walls
28.0
[...] Prince of Darkness has been performing extremely well after all its buffs and this is nice after it underperformed for so long, but the round 81 change to counter reduced Bloon Children with bonus Graveyard per pop has made it sustain high levels of graveyard too easily, this bonus has been lowered a little.
~ Ninja Kiwi
  • Buff Affected by Monkey Sense providing Camo Prioritization
  • Nerf Prince of Darkness ‘bonus grave' after r81 reduced from 7 -> 13 to 7 -> 10

Bug fixes[]

23.0

Trivia[]

  • The Prince of Darkness is sitting on a throne that does not rotate with the tower's aiming.
  • Before update 2.0, this upgrade used to be Soulbind. The Soulbind upgrade unlocked an ability that allowed the player to bind towers to the Wizard and sacrifice them for extra lives if bloons got through.
    • The graphics for the Soulbind/Prince of Darkness upgrades remained the same through the update; both towers have/had the same graphics.
  • The Wizard moves its hands when attacking and summoning bloons.
  • Note that similar to its predecessor, the Wizard does not have to pop the bloons himself, they simply have to be popped within his presence to become undead.
  • The undead Bloons, MOABs, and BFBs aren't affected by the Big Bloon Option.
  • From Version 11.0 onwards, due to a massive range buff, Prince of Darkness has more range than Arcane Mastery and their subsequent upgrades.
  • The tower's name might be a reference to a movie of the same name which is about a necromancer.
  • There was a glitch with this tower and Necromancer: Unpopped Army where if you exit your current game, go to sandbox, pop some bloons and spawn zombies, then go back and start the round, your Necromander or PoD would spawn the zombies from your sandbox session allowing for easy zombie spawns.
    • This was patched as of Version 18.0. Now the "graveyard" stores all popped bloons from last round, and the amount of bloons sent there will be constant.
    • ISAB posted a couple of videos showcasing the "Prince of Darkness glitch", the latest being the video "Zombie Bloons Are A DISASTER On This Map (Bloons TD 6)", which he used to attempt to beat a certain challenge set on Dark Castle Medium CHIMPS with higher HP Ceramics and higher HP but slower MOAB-class.
  • With the Version 21.0 buffs, one 0-2-5 Prince of Darkness can almost fully solo basically any round on Logs CHIMPS except Round 97 and 100. Additionally, a multitude of 2TC combos with Prince of Darkness were done within two days, with a majority within even a single day: Inferno Ring, Perma Charge, The Anti-Bloon, Pre-Emptive Strike, Carpet of Spikes, MOAB Eliminator, Admiral Brickell, First Strike Capability, MOAB Domination, Churchill, and Avatar of Wrath
  • The description for Prince of Darkness was changed to include buffing all other Necromancers, and has been confirmed on Version 18.0, although the description may have been changed well before then.
  • Within the first day of release of the Dartling Gunner, all Tier 5 Dartling Gunners have 2TC combos with Prince of Darkness.
  • The Version 23.0 nerf to Prince of Darkness was intended by Ninja Kiwi to have been incorporated in the previous update, but they pulled it back due to previously unresolved bugs while attempting to balance it out. The new balance change has made Prince of Darkness more reliable at stockpiling but less capable of maxing out its graveyard damage stacks.
