Call into existence a 5-meter radius vortex of snow and ice for a number of rounds equal to the character's Spell Rank with this spell.

All caught within the radius must make a dodge roll each round or take Frost damage equal to 1d6 per rank of the caster's Power Modifier. This damage ignores up to POW ranks of soak or Cold Resistance.

Each round, the vortex moves. If the player maintains control over the vortex, then they choose which direction it moves, and it moves up to Power meters in that direction.

At the end of the duration, the player may expend 5ep a round to keep the vortex in existence.

If the player controls the vortex in a specific round and/or invests upkeep into the spell, then they are effectively devoting part of their concentration to the spell, and their Gnosis is at -1 for that round for all other purposes.
