As you gain more levels in Corruption you'll eventually unlock the Powers system. A pseudo talent-like system that will allow you to take various new abilities that range from class spell modifers, procs, flat stat increase, stat conversions to other stats, damage increasing effects, and even brand new abilities and effects for your class!
You can access and view Corruption Powers at any time. Just find the Corruption Manager npc, mainly located in the mall, and interact with her. Each power has its own level requirement that your Corruption level must meet before you're able to learn the new ability. To unlearn the abilities you will need a Fel Shard which can be bought from Kami Stickyfingers ingame for 100g each. You will sometimes get these shards from boss kills and as played time, they're are not account-bound, so please keep that in mind!
Every class has its own tab within the Corruption Powers UI. These class tabs will have every power that effects your class related abilities in any shape or form, even offering you new ones!
The Tiered tabs will offer you powers that effect your stats, such as giving you more armor or strength. Some tabs might even offer you powers that will convert one stat into another, such as a certain % of your strength giving you spellpower! Some powers may even give you a significant damage boost when fighting certain enemies!
This system is always expanding with new powers, so check it often!
The Corruption Powers system is fork of a Custom Racial UI system. We're currently unaware who created the Custom Racial UI system but all creation credits go to them and when we discover who made it, proper credit will be posted here.
