• Barioth's head threshold is 3 instead of 4
• Fixed Viper Tobi-Kadachi Tail and Legs
• Discovered what the Unknown Part of Deviljho does: when it performs its counterattack, if you hit it, it makes it fall backwards and the flinch counter of this part increases.

Also, it seems that Savage Deviljho performs its counterattack when the flinch counter (of Counterattack) is even. When the counter is odd, S. Deviljho just stops.
