Hello. I have seen some pretty talented artists making mods, I thought to leave suggestion here in case anyone is interested. Nefarious Nekomancer from game called Trove, basically the look is called that but actual class is Tomb Raiser in its name. Here is the image that modder could use to base the creation on. This alone would be pretty sweet.

But if the interest to make even more than only skin, such as whole reception, I can summarize couple important parts that could be used for this. The difficulty would probably be either around star of the city or impuritas. Tomb Raiser has immunity to stagger and is rather resistant to damage too, but does not have ridicilous amount of health. The Tomb Raiser summons up to six minions in battle, they are somewhat weak, but they will be re-summoned after 2 turns of each dead minion, so this makes it difficult to deal with Tomb Raiser solely which is why it is high in difficulty. Tomb Raiser has it's own attacks too of course, primarily focusing on lightning magic. Sometimes banshee appears, that is unkillable and will heal minions (not Tomb Raiser) and then it will perish automatically next turn, this would probably happen every maybe 5 or 6 turns? And one last thing that Tomb Raiser can do is summoning something called Grave Goliath, which is like Tomb Raiser's big minion, very powerful and can take quite a lot of beating, so it is recommended to block it's attacks and focus on Tomb Raiser instead as after you beat Tomb Raiser, the game is reception is won.

The last thing. I would personally do this myself, but am sadly no artist and I have no idea how making reception either would work at all. Lack of art skills alone makes this pretty much impossible for me, which is why am leaving suggestion in case anyone wants to do this. If anyone takes this on, do let me know. Thanks for reading.
