House Rules: Traps

Additional Trap Creation Rules

  • Magic device traps now have a limit to how many times they can be reset, tracked as charges akin to magic items. Additionally, automatic resets now have different time delays before resetting.
  • Increasing the number of charges increases the cost of the trap.
  • For automatic resets, trap costs increase the shorter the delay is.
