When equipped, the ring makes a lightning sound and can be right-clicked to activate an emote. When the emote is performed a thundercloud appears above the player's head. This does not work when under a roof (including POHs); however there are some exceptions, including the area outside Kuradal's dungeon. The thundercloud does not follow the player and simply stays in the space it was spawned. The cloud lasts approximately 20 seconds, and the player must wait a further 20 seconds to activate the Summer storm ring again. This cooldown is shared with the Summer sun ring.
