I have a pretty good idea of where they are drawing their list of potential spells from. Its the same RPG book they get some other bits of lore from especially when you consider what they have done in Conan Exiles so far, Isle of Siptah, and Age of Conan.
And many of our spells we have now are sort of derived from that, some are just created for Conan Exiles itself. But many of the spells don’t really pass the litmus test.
Spells like Speak to the Dead, Demonic Pact, and other spells that require role-playing to function well are likely going to be right out. Those don’t even need any sort of mechanics since players can use emotes and roleplay to use them already.
Then there are others that just aren’t really feasible or even that fun to use. Either because translating turn based dice rolls to real time action doesn’t always work, or because the mechanics needed for the spell would need to be individually developed just for that spell and the impact is minimal.
The other consideration is do we already have something that fills the niche a spell is trying to accomplish? If so, what’s the point of a spell that will likely be a nerfed version of that.
Like one of the things that some people have requested is more combat oriented magic. Well we already have swords, spears, and bows. Combat is pretty well covered there. Why expend sorcerous powers, risk one’s body or soul in a dangerous incantation when they can just stab a foe with a knife? Just remember if a sorcerer is in combat, their other spells and contingencies have failed.
