Master of Heart Lv.4
心の師匠 Lv.4
Master of Heart Lv.4 is a Battle Cats stage in Street Fighter - VERY HARD -. It costs 210 energy and sends 7 enemy spawn lines — led by Ryu (Enemy) as the boss — against a 1,050,000 HP enemy base, and clearing it rewards 29,610 XP. Its enemies carry the Angel, Aku, Alien and Floating traits, so cats that target them do the most work here.
