Scroll of thunder cloud

The scroll of thunder cloud is a t5 conjuration scroll that calls forth a large grey cloud that deals heavy damage. Inside of it if you swing your weapon an additional 5 recoil damage is taken every time if you are not on the casters party, it will also have a rare chance to hit someone with white damage, similar to the ring of damage, that deals around 40 to 60 damage representing getting struck by lightning. This effect will last for about 30 seconds.
