Gates of the Underworld: Boldizsar boss fight

[Nick 'Volrath']

Anyone defeated him?

I am watching old youtube videos (epic store version of the game) and seems the fight has become way more difficult.

At 150 heatlh he creates versions of himself, like 6 or 7 and becomes invulnerable. No way to defeat him (level 19 party).

Any help? :(

I killed him with mage "dots", kampo, kela and csilla, with luck and a lot of resurrection spells and potions.
The hardest fight until now.

I got him by focusing them down with archers, but I should warn you: none of that stuff unsummons on his death, so killed him and still had to mow through 4 mages and 2 succubi after the fact.

The second hardest battle in the game. Easist way is simply going for him right away so he summons less copies of himself since they are significantly more dangerous than the succubi and wizards he summons at the start. I do think however that its a battle the devs need to look into.

Edit: Final battle with stronger enemies was harder.

I have a level 17 party and am really frustrated with this fight. I have tried respecing, changing the party composition, and just about anything I can think of and still can't seem to get past this fight...
You can't really grind for higher levels, and there doesn't seem to be any way to adjust the difficulty (playing on "moderate challenge" as it is), so I am not sure I can finish the game. I hate to get this close to the end and not complete the game, but not sure there is a way forward at this point. My main character is kind of weak (I made an archer/ranger), but I am stuck with him in the party--don't think I want to start over with a different class...so kinda stuck for an answer at this point...Too bad as I have really enjoyed the game up to this point...
