1-level Evocation
An orb of radiant power forming a line 60 feet long and 5 feet wide blasts out from you in a direction you choose. Creatures in the orb's path must make a Dexterity saving throw or take 2d10 radiant damage, or half as much on a successful save.
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.
