The Armor of Truth is a heavy armor set. When you set an enemy off balance, your Weapon Damage is increased by 450 for 10 seconds.
Armor of Truth can be a very powerful set with the right build, as it increases your Weapon Damage by a huge margin. The 450 Weapon Damage also can be amplified with percentage modifiers, like Major Brutality granting 20% increased Weapon Damage. That way you can end up with over 550+ Weapon Damage from this set alone. Off balance is caused by certain skills, for example Power Lash from Dragonknights, from the Champion Points perk Tactician, and various other sources.
This set works well for "tanky DPS" builds, for players who want to combine damage/offensive abilities (Weapon Crit, Weapon Damage and Stamina) with survivability (Heavy Armor).
Armor of Truth is part of the base game. It can be found in Darkshade Caverns I and Darkshade Caverns II in Deshaan. Each set item is bound on pickup. You can acquire heavy armor, weapons and jewelry of this set in the Dark Elf motif style.
