Vitriolic Sphere - Stoic

You channel the corrosive energy of your Inner Flame into a precisely controlled, glowing, 1-foot-diameter sphere of supernatural acid. The sphere streaks toward a point you choose within range and bursts in a 20-foot-radius Sphere.

Each creature in the area must make a Dexterity saving throw. On a failed save, a creature takes 20 Acid damage and an additional 10 Acid damage at the end of its next turn. On a successful save, a creature takes half the initial damage only and suffers no delayed damage.

Stoic Restraint. This spell is restrained by your Stoic State, decreasing both its initial and delayed damage dice from d4s to a fixed value of 2 damage per die. Consequently, its normal 10d4 initial damage becomes 20 Acid damage, and its normal 5d4 delayed damage becomes 10 Acid damage. The delayed damage retains its normal timing and occurs only when a creature fails its initial saving throw.

Your Stoic State improves your Ranger spell save DC, making the explosion more difficult to resist at the cost of raw damage.

When you cast this spell, you can use Red Colour Conversion to change all Acid damage dealt by this casting to Fire damage, including both the initial explosion and the delayed damage at the end of affected creatures’ next turns.

Using a Higher-Level Spell Slot. The initial damage increases by 4 for each spell slot level above 4th. The delayed damage remains 10 regardless of the spell slot level used.
