The effects of your traps last twice as long.
Benefit: An extended trap’s effects lasts twice as long as normal. A trap with a duration of concentration, instantaneous, or permanent is not affected by this feat. This only affects the duration of the trap’s effects, not how long the trap remains before breaking apart. An extended trap uses up a trap slot one level higher than the trap’s actual level.
