So the Necromancer skill
Skeletal Arcanist is essentially a shock based skill, however it doesn't proc the
Shock Weakness from the set
Elemental Catalyst. I understand why this is and that it's because the set doesn't register the attack coming from your character specifically, but it is a skill that you use and it is indeed tied to you so I don't really understand why it isn't considered in the proc conditions. Is this possibly a bug, or is this intended. Maybe
@ZOS_GinaBruno can give us further insight into this topic.
