Is there any mods that improves the encounter with the lesser demon lord in Ust Nasta?

I'm not speaking about the xp rewards (for that there is unbiased quest rewards inside atweaks), but a mod to improve the deal you make with him.

Rather than getting a shit halberd (the mist) or 20k money, there should be a suitable reward. You are giving him a boon that would have warranted an alliance (!!!) with the drow to siege the elves, and all you're getting is a shit halberd or 20 k?

Given that there is probably no mods, I ask everyone that reads for a brainstorming. What boon would a lesser demon lord offer for these eggs?
