Sacred Haven of Debauchery

even though you haven't played HoMM, I still need your advice. I got a new level, but I don't know where to invest it. Right now, I have a Wizard at level 20, and I can get to level 21 and become an Epic Wizard (if I choose another class, I'll just become an Epic hero). So, I'm thinking of taking the Wizard and learning some spells, even though they're not that important, and getting a cool ability (I noticed Epic spells that allow you to summon a dragon or a mummy – these are two different spells, so I still need to choose between them, but a dragon will probably be better) or taking an elite class, which is similar to a Necromancer. At the beginning, its bonuses are not very good, but later they become good, although it's not a fact that I will have time to level up before the end of the game and they will appear, but it would be fun to walk around with a bony hand, I think.

yes, I dragged that vampire-mage down and went lower, and there was a dracolich.
