Arctic Armour

Arctic Armour is a defensive skill that protects the player against physical and fire damage while stationary, leaving a trail of ground ice and chilling enemies when they hit him. The trail of ground ice lasts 2.5 seconds at level 1 and increases for every level after.

Skill Functions and Interactions

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.

Blood Magic: A 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.
