When initially purchased, the armour starts at tier 25. If your Defence level is 50 or higher, equipping the armour results in the following message: The armour adapts to suit your current abilities. and upgrades the armour to tier 50 or 75 based on your Defence level. When logging into a free-to-play world, the armour will revert to its tier 50 variant.
The armour's set effect adds a 1% chance per piece worn to deal a critical hit (95–100% damage for that attack) against enemies in combat. Wearing at least 3 pieces is required to gain this set effect, similar to how the other warpriest armour sets function. When the effect activates, a blue column of light appears over your target, and the following message appears in the chat box: "You channel the power of the beast and deal a critical strike!"
Until the update on 15 June2015, only one piece of the armour set had to be worn to have a chance for the passive effect to activate.
During the world event, this armour set cost a total of 12,000 Reward Currency.
Before an update on 10 July 2017, the Tuska warpriest stayed Tier 75 in free-to-play worlds. This was done by simply moving from a members to a free-to-play world while having it equipped. This was just a bug, and was fixed.
