Traps

Magic Traps

  • A successful Search check (DC 25 + spell level) made by a rogue (and only a rogue) detects a magic trap before it goes off. Other characters have no chance to find a magic trap with a Search check.
  • Magic traps permit a saving throw in order to avoid the effect (DC 10 + spell level x 1.5).
  • Magic traps may be disarmed by a rogue (and only a rogue) with a successful Disable Device check (DC 25 + spell level).

Provided for each trap is its Challenge Rating (CR), the area the trap affects or its attack bonus (whichever applies), the amount of damage it inflicts (in parentheses), and the DCs for saving throws or skill checks to find, avoid, and/or disable the trap.

Designing a Trap

Magic Device Trap Cost

Creating a magic trap costs experience points and gold, just like creating magic items. If a trap is a one-use device, the cost for creation is 50 gp and 2 XP, both multiplied by the caster level. If a trap has multiple uses (or functions continually), the cost for creation is 500 gp and 20 XP, both multiplied by the caster level. Devising and placing a magic trap not covered by existing spell effects is just like creating a magic item. Building a trap-filled dungeon filled with magical dangers is thus a costly process.
