Tempest's Power

The cape creates a sphere where in where visibility is brought down to zero due to a blizzard obscuring vision to those (besides those who she transfers her both vision and immunity to heat and cold to). The sphere itself starts out with a radius of 10 meters, while slowly expanding by one meter every turn. This caps out at 50 meters. When the sphere is released, the energy that was stored up during the blizzard escapes, causing widespread damage. This scales with time.
Tier 1: Caused by the aura being up for 1-5 rounds. This causes an explosion of heat around her, dealing minor burn damage to those who fail a guts roll of 3 or more. This does not apply to those who she has transferred her immunity to.
Tier 2: This is caused by the aura being up for about 6-10 rounds. When released, this can cause moderate burn damage who fail a guts roll of 3+. This,again, does not apply to those who she has transferred her immunity to.
Tier 3: This is caused by the aura being up for 11-15 rounds. When released, this can cause nearby buildings to collapse and deals a critical burn to anyone inside who does not have resistance or fails a guts roll of 4+. If they tank the hit, it goes down to a moderate wound.
Tier 4: When the aura is up for 16-20 rounds, this will cause nearby buildings to collapse and inflict a critical burn wound to anyone inside the aura who does not have resistance or fails a guts roll of 5+, and if they do, they still with get a moderate wound. If the guts roll falls below 3, this inflicts death sentence.
Tier 5: Anyone or anything inside of the aura that does not have resistance after 21+ rounds is instantly vaporized.
