Trap Expert

Saboteur
Level 10: Your can now set mines with tripwires around it. When an unsuspecting foe (or blind enough ally) gets within 5ft of the activation radius, they trip the line, pulling the mine 5ft in that direction, where it will then activate.
Level 15: Allies will no longer take damage from your mines. Increase activation radius of mines to 10ft.
Level 20: Increase mine effect DC by +5. Deal an additional 2xTier of mine (Minor is tier 1, devestating is tier 5). Max 10 additional damage with each devestating mine. Mines that deal no damage instead have an additional DC of +5, bringing the bonus to +10.
