The Stricken Family CR 3
Notice Wisdom DC 10 (to notice the room start to grow cold); hp 6
Trigger proximity; Reset automatic (24 hours)
When the room explodes into rot and fungal decay, every PC in the room must make a DC 14 Fortitude save to avoid contracting Vorel’s Phage (see page 27). Once the room reverts to normal, those characters who failed their saves can see tiny splotches of mold and tender red bumps on their flesh, but until the disease has a chance to incubate, these symptoms remain invisible to others.
