I’m really curious.
Aether SS already loses out on the damage from Blood Boil node as neither Bleeding nor Vitality Decay have any use.
The 3 seconds bonus duration means little because by default SS already has 100% uptime (5s recharge with 6 second duration) and because SS is a debuff effect, mutliple uses don’t stack (So unlike say, Sigil of Consumption, you can’t turn +duration into more stacks of the skill dealing damage)
On top of Vit to Aether being relatively simple to convert (Chains of Ygraad + a weapon = 100% global Vit to Aether) the transmuter ends up feeling kind of redundant when all it really does is reduce your damage and make your build marginally less piano.
Kind of feels like it should be providing additional benefit to make up for Blood Boil being useless for damage for Aether SS.
