Ghosts in the Storm

FEAT 12
Activity 1 action

Clouds, like eager pets, are drawn to you and to those in your good graces. Fast-moving gray clouds surround you, as well as your allies while they're in your kinetic aura. Anyone surrounded by these clouds gains a +2 status bonus to Reflex saves and Acrobatics checks.

When an affected creature uses a move action, clouds dance around it. Until the start of its next turn, it's Concealed, and its Strikes gain the Shock rune.

Effect: Ghosts in the Storm (Move)
