Campaign: Dungeons of Drakkenheim
Researching the Spell: A character who can cast 3rd level spells can research Ride the Rifts. To complete the research, the caster must spend 6 days of downtime and 300 gp.
Contaminated Spell: When you cast this spell, you gain one level of contamination.

A stroke of eldritch lightning forming a line 60 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must succeed on a Dexterity saving throw. A creature takes 10d6 lightning damage on a failed save, or half as much damage on a successful one. You then teleport to an unoccupied space you can see within the line’s area.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 2d6 for each slot level above 3rd.
