Arctic Armour is a spell that reserves mana to grant the caster physical and fire damage reduction while stationary, chill enemies that hit them, and cause them to leave behind a trail of chilled ground while moving. Less Damage taken when Hit: This modifier is applied at the very end of the damage calculations. As the damage reduction is only applied on hits (including reflect), damage over time effects like burning are not affected. Chilled ground: Ground ice chills anything standing on it. This does not stack with other chills. Mana Reservation: Arctic Armour is affected by all mana reservation modifiers. Blood Magic: A Arrogance Support gem can be linked to Arctic Armour or the Blood Magic keystone can be allocated to make Arctic Armour reserve life instead of mana. The Perfect Form : This unique item gives Arctic Armour 100% reduced mana reservation.
