Vulkan Pants

The Vulkan Pants are pants made by Morlok. As with the other Vulkan Series parts, they require 3,500 Faction Credits and 250 Zeta tokens to purchase from the faction armory. Wearing this armor piece also reduces projectile damage taken by 15%.

Because of its health bonus, health regeneration, and projectile damage resistance, Vulkan Pants were formerly used in builds that focused specifically on reaching the highest wave possible in Apocalypse mode. However, such builds have since been made obsolete due to the addition of armor penetration scaling in 1.10.2. Due to its low faction cost compared to other armor as well the aforementioned bonuses it provides, Vulkan Pants can still be a good piece to use for low-mid level players before obtaining stronger Black armor.

Trivia

 * Despite the armor itself canonically offering protection from the extreme heat of Zeta, it actually doesn't provide the most thermal damage protection in-game.
