Water Conservancy (Merciless)
水辺環凶保全運動 超極ムズ
Water Conservancy (Merciless) is a Battle Cats stage in Top of the Bog. It costs 200 energy and sends 10 enemy spawn lines — led by Kappy Jr. as the boss — against a 1,200,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Floating and Relic traits, so cats that target them do the most work here.
