Catch Flame

When an enemy creature enters your melee range you can use your reaction to ignite flames from your hand. The creature has to make a dexterity saving throw. It takes 3d10 fire damage on a failed saving throw or half as much on a successful one.

This spell can only be used this way.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d10 for each slot level above 1st.
