De Launcet's Crystal Beam

You create up to 3 levitating crystals within 30 ft of you that fire a 60 ft continuous beam of damage, choosing between Cold, Fire, Necrotic, Lightning, Radiant, or Force damage.  (You can only cast one type of damage per use, but can cast the spell again to create a second or third crystal of a different type.) Anyone hit or in contact with the beam takes a continuous 2d6 damage per round. 

You can use your action to move 2-3 of the beams trajectories up to 90 degrees, or your bonus action to move 1 beams trajectory. 

When you cast this spell using a spell slot of 3rd level or higher, the initial damage increases by 1d6 for each slot level above 2nd.
