Ok so Oma is literaly TLDR (might read on my next playthrough, right now I was just skipping to see what each wish could do) and gotta say 2 things:
1) I'm honestly surprised that we got an NPC with C-Cups breasts.
2) Ok some of the wishes are honestly usefull, Think I'll go for the Regen and Teleport one next time I play (could go for more but eh, I'm a sucker for happy endings so I'm freeing the genie.)
About that...
Regen
Trail rations are cheap and are full heals to the entire party after every fight. Regen for 1 out of 3 members is...
Teleport
Dungeons leglock you inside, waystones are everywhere, Lingering embers exist. Still pretty convenient.
Wealth
It
doesn't stack with other sources of extra money. The other Kinu quest (if you can force yourself to sit through it) has one that also provides double EC.
Don't pick this.
Power
It hits pretty hard. On turn 3
Storage
Honestly more QoL then anything. But the convenience it provides is potentially probably nice. 10 camps instead of 5. 6 Rations instead of 3. Realistically if you take teleport you wouldn't need this given you can just pop out at the wayfort whenever you want. And dungeons don't last long enough to burn through even half of an original stack of items.
Anyways, Yoma was pretty interesting. B said it was a passion project and it showed. Every companion has things to say and different interactions when weighing in and preventing you from making an ass out of yourself. Every companion additionally has a different dialogue line when asking "what" they wished for though I found this to be the weakest part due to the majority of the characters wishing for nothing with various flavors of altruism. It defeats the concept of temptation if nobody is tempted. Things like the previous masters wishes are neat and B did a decent enough job explaining how an eternity in nothingness could be pretty agonizing.
The sex scenes were pretty inventive (but there's so few of them.).
Jesus, the new art for the Hellhound is just crazy good. I just want to breed cuddle her and never ever leave.
Though given the hellhound is a completely different character now, sort of fits.
DCL's art was informed by the obvious inspirations of the hellhound in general. I'm of course referring to the one from MGE. Now that the hellhound has had her personality uplifted into another "honor and duty" type, it probably wouldn't have fit.
