Expansive Form

You have learned how to suck in moisture to expand your mass. As an action, you may expend 60% of your maximum of magicules in order to put a number of stacks on yourself of Enlarge (from Enlarge/Reduce) equal to the cube root of your magicule maximum. Attacks count as ability checks for purposes of this feat, and each additional stack of Enlarge boosts the size of the die for that stack by 1 (d4 -> d6 -> d8 -> d10 -> d12). Additionally, each stack past the first doubles the total number of dice you get to roll for advantage purposes relevant to the spell Enlarge/Reduce (PREREQUISITE: the Slime class)
