Trigger A living creature enters the portal tunnel
Effect As the PCs begin to pierce planar boundaries, they feel they've caught the attention of the archdevil Barbatos, ruler of Avernus. Each creature in the tunnel must attempt a DC 45 will save. The hazard then rolls initiative.
Critical Success The creature is unaffected.
Success The creature is Stupefied 1 for 1 round and Frightened 1.
Failure The creature is Stupefied 2 for 1 minute and Frightened 2.
Critical Failure The c
Disable DC 50 arcana (master) or DC 50 religion (master) to allow the group to traverse along the portal tunnel; six total successes are required to complete the journey; a PC who succeeds at a DC 48 acrobatics, DC 48 athletics, or DC 48 survival check as a 2-action activity grants themselves a +2 circumstance bonus to AC and saves against the hazard's routine for 1 round (on a critical success, they can also grant this bonus to one other PC)
