Abandon Flesh

9-level Transmutation

Casting Time: 1 action

Range/Area: Self

Components: V, S

Duration: Concentration, up to 10 minutes

Your flesh temporarily melts and slides off your bones as your skeleton transforms into a grotesque, monstrous form fueled by osteomantic magic. Until the spell ends, you can’t cast spells, and you gain the following benefits:

You gain 70 temporary hit points.
You are immune to necrotic and poison damage.
Your limbs become natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal bludgeoning damage equal to 4d6 + your spellcasting ability modifier, instead of the bludgeoning damage normal for an unarmed strike.
Your size doubles in all dimensions, and your weight is multiplied by eight. This growth increases your size by one category—from Medium to Large, for example. If there isn’t enough room for you to double your size, you attain the maximum possible size in the space available. Your weapons also grow to match your new size. While these weapons are enlarged, your attacks with them deal 4d6 extra damage.
You advantage on Constitution and Strength checks, as well as Strength saving throws.
You can’t be charmed or frightened.
You can attack three times instead of once when you take the Attack action on your turn.

Immediately after the spell ends, your flesh returns back to its original form.
