Legend of the Night

"We turn to him, when all hope is lost..."

- In-game description

 (also referred to as LotN or The Night) is the last upgrade on the third path for the Super Monkey in Bloons TD 6. It gains a passive ability that summons a black hole at the end of the track if any bloon (including all MOAB-class Bloons, even BADs, but not Boss Bloons or Golden Bloons) escapes. The black hole ability absorbs the first bloons that leak and prevents the player from losing any lives for 7.5 seconds before disappearing, and it has a long global cooldown of 2 minutes. The tower also becomes much stronger with a slightly longer range (+4 range to be precise), +15 pierce (from 7 to 22), base damage increased by 3 (from 2 to 5), and dealing 8 damage per hit to MOAB-class Bloons or 7 to Ceramic Bloons.

It costs $170,000 on Easy, $200,000 on Medium, $216,000 on Hard and $240,000 on Impoppable.

Summary
Legend of the Night is the second-most powerful tower in the entire game (excluding paragons), second to the True Sun God and its special variant (Vengeful True Sun God). Thanks to its black hole passive ability, it can temporarily tank bloons (except Boss Bloons and Lych-Souls) without losing lives, equivalent to instakilling leaking bloons but without the income gain. This makes the Legend of the Night excel at extreme late-game (Rounds 101+), as a safety net for leaks, since it can tank any bloon by effectively deleting them. However, Version 30.0 nerfed Legend of the Night's passive ability to have a global cooldown instead of a local one, preventing chained use of the passive ability.

Outside of its special ability however, it is almost never used as it is simply too expensive compared to other Tier 5 options that can beat the game just as easily as Legend of the Night but for cheaper.

However, alongside The Anti-Bloon, Legend of the Night is required as a special sacrifice to the Vengeful True Sun God, making it not accessible until the Vengeful True Sun God is sold. The most effective tactic is generally to exchange the Legend of the Night's ability for the 2x damage, as the increased DPS is more valued than the Legend of the Night's comparatively weak attack and niche ability.

Tips

 * The Legend of the Night can be placed along straight lines to increase the usage of its fairly large pierce.
 * Setting the tower to 'Strong' allows it to prioritize high health MOAB-class bloons, which is its specialty.
 * Do note that this means that if it is focusing on a higher-tier bloon, lower-tier MOABs may still pass through defenses.
 * This upgrade synergises very well with Elite Defender and Bomb Blitz since it can trigger those towers' abilities without losing any lives (although Legend of the Night is very expensive for such a synergy).
 * Deleting bloons with the passive ability will not reward cash.
 * Legend of the Night cannot instakill Golden Bloons with its portal, and attempting to do so will yield no reward.

Trivia

 * This tower, along with the Anti-Bloon, is required to create the Vengeful True Sun God, one of the most powerful towers in BTD6.
 * Legend of the Night is the second-most expensive upgrade in the game (excluding Paragons), with the first being True Sun God.
 * As of v17.0, the Legend of the Night is currently the only Path 3 Tier 5 tower in the game to have an ability.
 * Counting past versions of the game, however, it is the second tower to have this distinction, the first being the now-unused Soulbind.
 * While very expensive, a Legend of the Night was affordable as early as Round 173 on CHIMPS.
 * Legend of the Night may possibly (Though very unlikely) be a play on the word "Knight" as previously used in the path 3 tier 3 upgrade, "Dark Knight".
 * It is notably one of the few non-hero towers that use male pronouns in its description, the other being Super Monkey Fan Club.
 * It is also the first tower upgrade capable of one-shotting the BAD-Bloon, following 2nd Ezili with her lvl 20 MOAB Hex ability, and 3rd is the Navarch of the Seas (Monkey Buccaneer Paragon).
 * It is a reference to the local superhero, Batman.
