Extra Damage to Stunned

Extra Damage to Stunned is a projectile behavior characterized by dealing more damage than that tower's base damage to "stunned bloons" (bloons affected by a valid stun status effect) per hit. It is part of the damage types family.

Extra Damage to Stunned is represented on Bloons Wiki as, the upgrade icon for Artillery Battery in Bloons TD 6, since Heavy Shells is already used for Extra Damage to Leads. Extra Damage to Stunned is simply a subset of Extra Damage. Only two unique upgrades are known to exist in Bloons TD 6, and all are added in later updates: Heavy Shells and its later upgrades, and Sauda Level 6+.

All attacks require an upgrade to deal more than one damage to Stunned per hit.
