Trap Effects FAQ
Questions about this table.
How do I balance trap damage against my party's level?
Use the hazard or encounter guidance from your game system. This table supplies effects but does not set damage, saves, difficulty, or a target character level.
What makes a trap effect memorable versus annoying?
Memorable effects change the situation in interesting ways - splitting the party, creating a new problem to solve, or forcing an unexpected choice. Annoying effects simply punish without creating engagement, like unavoidable damage with no counterplay. The difference is whether the effect opens up new gameplay or shuts it down.
