Acid Arrow CS

You conjure a glowing arrow made of pure acid that streaks toward a target within range. Make a ranged spell attack against the target. On a hit, the target takes 2d4 acid damage immediately and an additional 2d4 acid damage at the end of its next turn. On a miss, the arrow splashes the target for half of the initial damage but no damage at the end of the target’s next turn.

A creature can use its action to scrape or wash the acid off itself or another creature within reach, ending the effect.

Higher Levels:

When you cast this spell using a spell slot of 2nd level or higher, the initial damage increases by 1d4 and the end of turn damage increases by 1d4 for each slot level above 1st.
