Thunder dome

when casted it creates an  area of dark clouds with purpule lightnings running trough it's terefying to look at and even worse to be in.

Extreme wind and complete darkness that is only illuminated by the lightnings shoting towards the unfotunate who is inside this horror this is truly more than just the force of nature.

Unlike a normal storm this spheare of dark clouds is stronger towards the middle, anyone within 10 feet of the centre will have disadvantage on saving throws.

note that when placed on debris the wind will pick it up and throw it around inside the storm, some times even outside this causes the whole area to be disadvantage zone and cause extra bludgening damage
