Arc Chain

Lightning strikes happen upon a creature who has a known presence.  This creature will take 2d6 lighting damage, and any creature standing within 5ft of the one who was originally striked, also takes 2d6 lighting damage which must be rerolled for these creatures. Any creatures within 10 ft of the One who was originally striked, is stunned losing there action for there next turn. If a creature's outside of the 5 ft lightning damage radius but still within 10 ft, it will have a chance to roll a constitution saving throw it must be higher then 16 or this creature will also be stunned.

At Higher Levels: 1d6 lighting damage will be add to each level of the spell. So a level 3 version of this spell will do 3d6 lighting damage
