Slave to Energy
エナジー奴隷
Slave to Energy is a Battle Cats stage in Realm of Whyworry. It costs 180 energy and sends 9 enemy spawn lines — led by THE SLOTH as the boss — against a 999,999 HP enemy base, and clearing it rewards 289,332 XP. Its enemies carry the Red and Black traits, so cats that target them do the most work here.
