The Fury of Hedera

Your limbs grow like the woody vines of the Hedera plant.  You increase to one size large and you have a 15' reach with 2 clawed attacks per round doing 2d12 +6 of slashing damage, while the extra 6 points of damage is for poison.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d12 for each slot level above 5th.
