The storm

Dark clouds roll in, the cool brisk air seems to pick up wind at first just puttingoponents faceing the wind at a disadvantage... rain starts to fall,  making the ground wet, which puts everyone else at a disadvantage.... and that means everyone... lightning strikes somwhere within the range of the storm... as the Strom goes on, the wind picks up pushing anything in its path (which slows down most enemies, but can completely blow away the smaller ones. (Constitution saving throws for smaller enemies) the lightning strikes more often, and the rain is falling hard... to the point where every attack will require a Constitution saving throw. Uppon death you can roll ether a minimul of 7 on a d10, to be struck and revived with half health and spell slots, or a 17 minimum on a d,20 for full revive and spell slots. Requires wisdom check to cast... if failed lightning will mostly home in on the casters.
