Finally got the "Storybook Ending Badge" It seemed most doable with necromancer concentrating on summoning skeletons. To achieve victory First points go in getting more mana, then concentrate on getting an alternate weapon (fire staff did excellent) so you can double the damage while enemies are poisoned. In mid game start rising hp or getting non penalizing protection. Worth investing on getting sprint to get out of sticky situations. Avoid infectious disease at all costs!
Thank you! ❤
