Perils of the Warp
Whenever you roll a natural 1 on an attack roll or saving throw, roll a d20. If you roll 5 or below, then you trigger the Perils of the Warp. If you roll above 5, the regular fumble rules apply. If you roll a 18, 19 or 20, you also trigger the Perils of the Warp, but it’s effects are beneficial to you.
