Acid Splash - Stoic

You create an acidic bubble at a point within range, where it explodes in a 5-foot-radius Sphere. Each creature in that Sphere must succeed on a Dexterity saving throw or take 1d4 Acid damage.

Stoic Restraint. This spell is restrained by your Stoic State, decreasing its damage dice from d6s to d4s. When you cast this spell, you can use your Red Colour Conversion feature to change all Acid damage dealt by this casting to Fire damage instead. Otherwise, the spell deals Acid damage.

Cantrip Upgrade. The damage increases by 1d4 when you reach levels 5 (2d4), 11 (3d4), and 17 (4d4).
