Berserk mode

Berserk mode (羅刹モード, Rasetsu Mōdo, lit. "Rakshasa Mode") is a unique battle mechanics in Digital Devil Saga: Avatar Tuner 2. There is some chance the party will only transform part of their body into demonic form, completed with darker skin and glowing gold eyes, whenever the party enters random battle during 7/8 (fair chance) or Max (higher chance) phases of Solar Noise.

During this mode, every party member will gain extra physical attack power and critical rate but their accuracy and defense drop in the same time. This mode only allows use of normal attack, physical skills and hunt skills (which consumes a portion of max HP), all attacks will be almighty elemental so there is no concern in doing damage to enemies with physical resistances. Essentially all party members are still "human" in this form, that means they do not possess the same resistance attributes as their respectively demonic form and is immune to Expel attacks innately.

Although the drop of accuracy and defense means a high risk gamble, the game actually guarantees escape during this mode regardless of difficulty. Since the second playthrough, player will receive a Berserker Ring in Underwater Cable which guarantees the whole team to enter Berserk mode regardless of Solar Noise phase, but it will not work in any compulsory battle.
