Conviction skill
This skill is not live yet.
Paladin-only skill. Basically, tanking ability. This makes poison less damaging, stuns less effective, etc. Basically, it keeps the paladin from dying in ways that are a bit more interesting than damage reduction.
This skill was originally called Endurance and was proposed to counter damaging status effects, but on 3/23/2015, GM Raesh wrote:
The Paladin Guild Skill is a big part of the design I'm working on, but I would be shocked if it keeps the name and concept of Endurance.
I think Paladins will be in a significantly better place once the barrier review is finished and they have a functional guild skill (Tentatively renamed asceticism) and revamped soul system.
In very broad terms I'm looking to revamp the existing soul system (including glyphs, smite, etc) to be powered by "Endurance" (Almost certain to be renamed - I'm in favor of Asceticism) and use that skill as a bridge to giving Paladins active ways to leverage & train their armor ranks.
