No Damage

No Damage is an attack behavior characterized by an offensive attack dealing exactly zero damage per hit to a specific type of bloon, even if directly supported by any means such as using the correct damage types or receiving external buffs. It is part of the damage types family.

No Damage is represented on Bloons Wiki as, the upgrade portrait for Submerge and Support in Bloons TD 6, depicting the supportive role that this upgrade represents. It is mainly in regards to base damage, and some forms of Extra Damage of the same attack can be applied to deal add more damage.

Most support-only attacks come with the No Damage attack behavior. Examples include Grow Blocker, Shimmer's shimmer, Signal Flare's secondary decamo blast.

Some upgrades deal zero damage to some bloon types but deal damage to other bloon types, strangely enough. This includes Glaive Dominus's anti-MOAB glaives, which apparently deal zero damage to non-blimps but deal bonus damage to blimps and bosses.

Most attacks require an upgrade to deal more than one damage per hit. Glue Gunners and pre-BTD6 Ice Monkeys have this attack behavior by default.
