Reanimate recently popped enemies as servants to destroy the Bloons.
~ BTD6 description

Necromancer: Unpopped Army is the fourth upgrade of Path 3 for the Wizard Monkey in BTD6. It causes all bloons popped by any tower near the Wizard to become undead bloons that travel towards the entrance and deal damage to bloons they touch. This upgrade also allows the Wizard Monkey to pop Purple and Lead Bloons through the summoned undead bloons. Each undead bloon affects from 2 to 11 bloons (by chance, equivalent to graveyard consumption + 1 pierce) and deals 2 damage per hit and lasts for 10 seconds. Undead Bloons are stored in a personal graveyard, local to each Necromancer, and can store up to 500 accumulated bloons popped for up to 2 rounds. Undead Bloons are spawned +10% faster for every 100 graveyard units, for up to +50% faster.

It costs $2380 on Easy, $2800 on Medium, $3025 on Hard and $3360 on Impoppable.

Necromancer: Unpopped Army is not a very strong tower due to its low cost effectiveness. It can deal quite some damage if it is allowed to gather undead bloons beforehand, but requires support against densely packed Ceramics and Rainbows, and does essentially nothing to MOAB-Class Bloons. Eventually, around Round 50+, the Necromancer becomes too weak, either losing to MOABs or large bloon rushes it is unable to handle.

However, since the 13.0 update doubled the damage done by undead bloons, this upgrade has become significantly stronger, though still in a support role. If placed in a good position, it can easily reach over 100,000 pops by Round 100.


  • ALWAYS provide support, whether it is another Necromancer: Unpopped Army or another tower. This reduces leaks while the Necromancer is summoning undead bloons.
    • This is especially useful on rounds where there are little low-tier bloons for the Necromancer to begin summoning and snowballing from.
  • Position it on areas of the track where you want the bloons to spawn by placing only that track within its range.
  • When placed near the start of the track lane, Necromancers can be used as effective anti-stall on single-lane maps. For even better performance, add even more Necromancers, add Prince of Darkness, and add Alchemist buffs plus other towers that deal effective MOAB-class damage (e.g. MOAB Maulers).
  • Unlike ability-based towers, Necromancers benefit the most from anti-stalling. This is because anti-stalling a round will minimize the depletion of the Undead Bloon graveyard and therefore will have more stored Undead Bloons for later rounds.

Update HistoryEdit

  • Buff Necromancer now summons 2-5 undead bloons instead of 1-3 undead bloons per summon.
  • Buff Necromancer costs less ($3500 --> $2800)
  • Buff Necromancer undead bloons now deal +1 damage.
  • Buff xx4 Necromancer Wizards now each have their own personal 'graveyard' of 500 capacity rather than 1 shared pool of 2000
  • Buff xx4 Necromancer Wizards will display their current graveyard size above their portrait next to their pop count. Any Bloons popped within the Shimmer radius of a Necromancer can be absorbed into that graveyard, but 1 pop will not fill more than 1 graveyard.
  • Buff xx4 Necromancer Wizards will now be able to retain any Bloons in their graveyard for 1 extra round before expiring
  • Buff xx4 Necromancer Wizard's Zombie lifespan increased from 8s -> 10s
  • Buff xx4 Necromancer Wizard's Zombie spawn rate is increased by a flat 10% for every 100 Bloons in the grave reaching a maximum of double attack speed at 500 capacity.



  • This upgrade along with Prince of Darkness are the only upgrades that spawn in "Undead Bloons".
  • Necromancer Undead Bloons are off-centered on tracks, similar to Bloons in early games of the BTD franchise.
  • Undead Bloons aren't affected by the Big Bloon Option. This also occurs with the undead MOABs and BFBs spawned by Prince of Darkness.
  • Strangely enough, multiple Necomancers can spawn additional Undead Bloons if only a few Bloons are popped (ex. 3 Necromancers will summon 3 Undead Bloons for 1 Red Bloon).
