Aspect of the Lightning Ram

You grant the aspect of the lightning ram to you or another willing creature you touch. Until the spell ends, the affected creature can use its action to start continuously summersaulting as the lightning ram does. While summersaulting this way, the creature gains a walking speed of 10 times the your spellcasting modifier, and can only use its action to stop summersaulting. While summersaulting within 5 feet of an enemy creature, they have to make a constitution saving throw. On a fail the creature takes 2d6 lightning damage and half as much on a successful save. Additionally any attacks of opportunity made against you while summersaulting are made with disatvantage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
