I didnt take glory beyond 1st lvl, i just say it would work in that way.
As for undead units at start, i only found ghosts in sunset islands, on boat that you rise from sea with spell, all other undead units i found so far were regular zombies and some skeletons(both useless), only 150 archers, and i can lead 300 now. So i bought 60 ghosts, and after 10 battles i have 400 in reserve
Mirabella already gave bonuses for griffins so i just thought you missed moral.
Good find with rina black knight.
Holy indulgence quest is a bit much, 10 times more then other quests you get at that islands, so i thought it was mistake.
Ghosts are a bit tricky, i use half my spells to keep them in check(heal mostly), but it`s even harder against huge stacks of low lvl units like 600 devilfish(or something in that area) vs 50 ghosts, i end up with 200 ghosts and spend 4 spell cast to get them back in control

They already have -100 magic resistance, so i think no need for -fire also(maybe 10-20%).
Enchanted hero, yea i did have a bit strange situation with them

Against lucky james, he cast enchanted hero on his swordman, and when i attack it with my ghosts they made 7500 dmg killing whole stack 120 ghosts. Swordman are physical dmg, so it`s impossible for them to make such dmg to ghosts.
Resurrection + necromancy havent try so far, cant find res spell

And i think there should be on penalty to undead because ghosts and vampires in bat form dont need it almost, but other undead will need resurrection normal, if you dont use evlin. Or necro call would be much better option, it`s undead spell, make it res undead units, good idea.
About ghost soul drain, any idea how to make it to rise number of killed units, not done dmg ? Exp : i kill 1 black dragon and get 30 ghosts form it, or when i fought spider boss in mines, i attack it 1 time(case fire breath on ghost) and got 80 ghosts from that attack, and didnt even kill spider. So how to change this tricky ghost ability ? It just doesnt make sense to rise 10 ghost, from 1 killed unit. Like necro call spell, you can rise undead units form corpse, but cant rise more creatures then are killed (like from killing 1 black dragon, i cant rise 2 bone. only 1).
And did you change something in lina charges ? As whitemage said here
http://forum.1cpublishing.eu/showthr...287#post364287, it`s something wrong. I dont remember how it was in original game settings, but it just broken

To much mana/rage per charge when lvlup max.
