• Frost
• Threat of Thassarian now also causes Rune Strike to use both weapons when dual-wielding.
• Unbreakable Armor: Cooldown reduced to 1 minute and changed back to granting 25% additional armor while active instead of flat damage reduction based on armor. The amount of strength granted has been reduced to 10%.
