Currently, the tooltip only tells you the different types of storms created
Glyph. Create a storm based on your attunement.
Fire: Firestorm.
Water: Ice Storm.
Air: Lightning Storm.
Earth: Sendstorm.
Assuming the wiki is correct, it’d be helpful to expand the tooltip to include the effects of each type of storm:
Firestorm: damages up to 10 foes in the area each second.
Ice Storm: calls down 18 shards randomly around the area inflicting damage and chilled.
Lightning Storm: summons 36 lightning bolts randomly around the area that deal damage.
Sandstorm: affects up to 10 foes in the area, inflicting damage and 2 seconds of bleeding each second and blindness every 3 seconds.
