'''Berserk ([[Ex]]):''' Due to the sppression suppression technique, iron birds which are not build for war are a little unstable. When a iron bird enters combat, there is a cumulative 1% chance each round that its altered programming gets stuck in a loop and the iron bird goes berserk. The uncontrolled iron bird goes on a rampage, attacking the nearest living creature or smashing some object smaller than itself if no creature is within reach, then moving on to spread more destruction. The iron bird’s creator, if within 60 feet, can try to regain control by speaking firmly and persuasively to the construct, which requires a DC 19 Charisma check. It takes 1 minute of inactivity by the iron bird to reset the construct’s berserk chance to 0%.
