Tweaked from 5eYou already know this as 5e Fireball — It's basically Fireball — a 20-foot-radius Dex-save blast — but acid instead of fire, cast a level higher, and it deals a second chunk of damage to anyone who fails at the end of their next turn. ✨
Hurl an acid globe exploding in a 20-foot radius for 10d4 (Dex save half), plus 5d4 acid at end of targets' next turn on a failure.

!The secondary 5d4 acid damage only applies on a failed save, so resistant targets eat only half the burst.

You create a globule of acid and hurl it at a point within range, where it explodes in a 20-foot-radius sphere. Each creature in that area must make a Dexterity saving throw. On a failed save, a creature takes 10d4 acid damage and another 5d4 acid damage at the end of its next turn. On a successful save, a creature takes half the initial damage and no damage at the end of its next turn.
Overcharge Tech. When you cast this power using a tech slot of 5th level or higher, the initial damage increases by 2d4 for each slot level above 4th.
