Lightning Strike: Instead of attacking the lightning snake may move around its opponents. Each being along it’s path takes 3d6 electrical damage. Characters may attempt a Saving Throw for half damage. Characters wearing metal armor have a -4 penalty to this saving throw. There is catch for the Lightning Snake. It cannot cross over it’s own body while doing this. If that happens then the snake “grounds” out. The creature explodes with a massive discharge of electricity causing 4d6 damage to all with 10 feet of any part of the snake. Save for half damage as above with the penalty for metal armor.

Shocking: When a character succeeds with a melee attack with an unarmed attack or with a weapon made of metal that character takes 1d4 electrical damage. No Save.
