Scorched Plains

Fierce atmospheric combat is waged above these badlands, the electromagnetic forces generated in the clouds soaring down in massive electric jolts in a panic-inducing frequency that blasts away whatever dares walk the scorched earth. At the end of every minute while in this region, roll d%. On a 1 or 100, lightning strikes down and hits a creature. Roll once for each group of creatures within 10 feet of one another or individual creature. When striking a group of creatures, roll randomly to determine which creature is hit. A creature that wishes to take the hit can make a DC 20 Dexterity saving throw to interpose themselves between the target and the lightning bolt. A creature hit by a lightning bolt takes 35 (10d6) lightning damage and is deafened for 1 minute.
