The Mechanics of Creating Traps

This is what I've pulled out so far...

Attacks Bonus

Attacks Vs. Armor: Trap Level + 5

Attacks Vs. Other: Trap Level + 3

Damage

If the trap consists of a weapon use the weapons's Damage. (Example Crossbow turret fires 2 crossbows, so 2d8.)

Probably safe to use the damage per level types as per monster guidelines for other types of attacks.

Attack Type

Target

Based on the attack type usually.

Perception Check DCs

Based on the level of the trap, and what the check results in.

Checks that give limited info Easy or Moderate DC.

Checks that give information on avoiding or dissabling the trap Hard DC.

Countermeasure DCs
