So here we are, time to face Goat, three Goats.
(First time it popped up, only 1 hour, and I was sleeping at that time.)


Tips:
For All, like Serpents Tower, you can't Swap cause of their On Escape attack
(Even you have tons of Hp, it's still very risky)

For Lil, Immunity with 90% Armor, DoT move set and DoT counter, better bring Immune Creature to ignore debuffs, Defense Shattering moves also can help you to shorten battle time

For Billy, IT-Stuns with 60% Armor, Stuns move set with Deceleration counter, same as Lil, Immunity can ignore Stuns, or go for heavy attack

For Biggie, IT-DoT with Tons of Hp, Buff move set with P-DSS counter, so better not hit this Goat before you charge up strong attack... or waiting AI's Mutual Fury to gain Atk buff? (But it's a trick after second round)
