Arcane Engineer [Skill]
You can render your spell traps mobile.
Prerequisites: Rune Magic, Arcana and Engineering as trained skills, 12th level
Benefit: Once per [Scene], when you create a spelltrap spread with the Rune Magic feat, you may render it portable for the duration of the [Scene]. As a move action, you may pick it up if it is within [Melee] range, which causes it to no longer be active. As a swift action, you may place it on any square within [Close] range and render the spelltrap spread active. At the end of the [Scene], this portable spelltrap spread disappears. Placing down the spelltrap spread is a [Surge] effect.
