Frequently Asked Questions
How do I build a custom trap from these tables?
Roll once on trap triggers ("stepping on the third flagstone"), once on trap effects ("a cloud of paralyzing gas"), and you have a unique trap. Add a dungeon trap description for extra flavor.
Do the traps include difficulty or damage numbers?
No. The entries are narrative descriptions. You set DCs, damage, and saves to match your party level and system.
Are wilderness hazards different from traps?
Yes. Wilderness hazards are natural or supernatural environmental dangers - quicksand, poisonous flora, rockslides, cursed groves - rather than constructed mechanisms.
