Feathergeddon II (Merciless)
一石三鳥Ⅱ 超極ムズ
Feathergeddon II (Merciless) is a Battle Cats stage in Invasion of Poultrio. It costs 200 energy and sends 11 enemy spawn lines — led by Poultrio as the boss — against a 1,300,000 HP enemy base, and clearing it rewards 18,800 XP. Its enemies carry the Red, Zombie, Alien, Black and Aku traits, so cats that target them do the most work here.
