Lightning [>>>] Blade three (electricity, evocation, primal) The storm giant raises one hand to the sky, channeling a bolt of lightning into the blade held in the other. The giant makes a greatsword Strike with a –2 circumstance penalty against each creature within its reach. It makes only one attack roll and compares the result against each creature's AC. This Strike deals an additional 3d12 electricity damage and counts as two attacks for the giant's multiple attack penalty.

Throw Rock [>]

Wide Swing [>] The storm giant makes a single greatsword Strike and compares the attack roll result to the ACs of up to two foes within its reach. This counts as two attacks for the giant's multiple attack penalty.
