>using a mod
it's an official feature in the newest Heroes sequel, and you can already use it in the public demo.
You basically have to roll 5 relevant secondary skills and upgrade them to max, to unlock an ultimate skill. Necromancer can either temporarily resurrect dead enemy stacks as friendly wights, or upgrade necromancy to work on every creature.
>not sure how this is relevant,
OP pic is necromancy skill in Heroes III, so I fail to see how it is -not- relevant?
