Stigma Skills
Since Aion has a balanced character system gameplay, it doesn’t matter whether you’re an Elyos or Asmodian templar – your default skill tree will still be the same. However, with the inclusion of the Stigma system, players will gain access to more abilities not normally learned from skill manuals by equipping Stigma Stones and customize their characters with their own set of chosen skills. The irony however, is that late in the game, players tend to use the same builds and stigma skills since they’re proven to be quite effective.
By default, characters can only have 5 stigma slots. They start with two equippable slots and as the character’s level increases, more slots become unlocked. Late in the game, certain quest lines late will unlock three additional “advanced stigma slots”. The advanced stigma slots can both hold ordinary stigma stones or the new advanced stigma stones. However, you can’t place advanced stigma stones to ordinary stigma slots.
