As a reaction, which you take when you are hit by an attack you can see or taking fire damage, you can create a block of ice around you. Until the start of your next turn, including against the triggering attack and damage, you have a +4 bonus to Defense and resistance to fire damage.
You can expend 1 additional mana or psi to increase the bonus by 2.
You can expend 1 additional mana or psi to trigger the spell when a creature that you can see within 18 meters is attacked. The attacked creature gains the benefits instead.
Ice Shelter. You can expend 2 additional mana or psi to instead become encased in ice as the damage against you is halved. For 1 minute/mana or until you end this feature on your turn, a non magical dome of solid ice springs into existence around you. The dome forms up to 30 centimeters away from your body in all directions and is 30 centimeters thick. The ice is opaque.
The dome is an object made of ice that can be damaged and thus breached. It has 12 Defense and 60 Health, and it is vulnerable to fire damage. Reducing the dome to 0 health destroys it.
