Thermal Nimbus

FEAT 4
Activity 1 action

You direct waves of warmth into or out of your kinetic gate to drastically shift the temperature around you. Choose cold or fire. You and allies in your kinetic aura gain resistance equal to your level to damage of that type. Any creature that starts its turn in your kinetic aura or moves into your aura during its turn takes half your level of the chosen type damage. Elemental resistance from a gate junction is cumulative with resistance from Thermal Nimbus.
