Black chains surround your arm before your arm ignites in flames, melding the chains into a gauntlet to your preferred design.
At the start of each of your turns you gain temporary hitpoints equal to your spell casting ability modifier. And when you cast this spell and as an action for each subsequent turn, you can choose one of these options listed below. When the spell ends, the gauntlet fades away slowly and lasts until the end of your next turn
Punch-Make a melee spell attack against a creature within 5 feet of you, and add your Strength Modifier to the roll. On a hit, a target takes 3d6+ your strength modifier in bludgeoning damage and is grappled by you if it is Huge or smaller. Grapple and shove checks made with this hand aren’t Athletics (spell casting ability) checks + your strength modifier.
Crush- You smash a grappled creature in your fist. The target automatically takes 2d6+ your Strength modifier in Bludgeoning damage and is restrained until the end of your next turn or until your grapple ends.
Toss- You toss a Huge or smaller creature backs number of feet away from you up to 5 x (your spellcasting ability + Strength modifiers). A Creature can make make a Strength saving throw to avoid being tossed. A tossed creature takes 2d6 bludgeoning damage, or twice as much of it collides with an object or creature that is a size smaller than it or larger. If you toss a creature you are grappling, you can choose to toss it down or any horizontal direction, and you can toss it twice as far.
At Higher Levels- When you cast this spell using a spell slot of 4th level or higher, the damage of your Punch, Crush, and Toss increases by 1d6 for each slot level above 3rd.
