If the spell you choose is a 1st lvl spell you can cast it for free every second time and if its a cantrip you can cast it twice . When the spell is active you can attack without weapons using Unarmed strikes whitch deal 1d10 Bludgeoning damage + damage equal to your DEX and STR modifier + 2d8 of Necrotic or Radiant damage which the caster chooses when they cast the spell . You can choose to stay in this form for a longer time than what the spell allows you to but take a point of Exhaustion for each 10 minutes ( the exaustion effects dont effect you untill the spell ends ) .

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the duration increases by 1 hour for each slot level above 3th.
