Sacrifice of Loyalty + Umbral Well

Hello,
Sacrifice of Loyalty (kulemak timeless keystone, more damage per undead minion power) and Abyssal Lich's umbral well ("Skeletal Minions you would create instead grant you Umbral Souls for each Minion you would have created") are not compatible (obviously).

It would be quite cool if they could be.

As is, Abyss Lich does not have an Undying Hate keystone passive which synergizes well with it, which is fine I guess, but it would be cool if something could be changed with Kulemak to enable a synergy there.

The Sacrifice of Loyalty did not take effect correctly
