Foreign Grasp

Once per long rest, when you use your Wild Shape feature, you can choose to channel a strange energy, allowing you to transform into creatures from other planes for 1 minute. To determine which creature you become, roll a d100. If the creature you transform into has a CR higher than half your druid levels (rounded down), you must pass a Constitution saving throw (DC = 8 + the creature’s CR x2) or become berserk and lose the ability to discern allies from foes
