I think it doesn’t work because it’s a demi summon. I dislike it from a thematic standpoint too because it’s just too flashy. I would rather have a faerie buff that lets Selene’s embraces shield and bonus fey blessing with shield stacks than moving it to the caster. I don’t think it’s a good mindset on SE’s part to remove yet more pet capability over addressing the root issue, which would admittedly be rather tricky in the searing light situation.
