In Howard’s work - which I’m very happy you at Funcom, on this game, have been trying to stay true too. Sorcery requires the utmost commitment. Right now, it doesn’t. If you want sorcery, you run to the tome, cast a few spells, remove corruption, and continue on your way. The only time corruption is locked is when you corrupt your attributes. I think every time you cast a spell it should lock your corruption, even if you reset due to a Yellow Lotus Potion. If your sorcery grows in power - more deadly, longer lasting, higher debuffs and buffs, etcetera. Then it would require true commitment - just like Howard’s universe describes it.
Side rant: I’d also like to see the spells such as slow fall have a radius that affects party members. If it supposed too already, it’s not.
I guess that’s why it’s called an adaptation…? There will be some deviation and artistic license. As with all IP adaptations, just look at The Rings of Power, some things remain true, but other things don’t. I think that’s to be expected.
I do believe at least a long debuff would be in order after mid to high level spells or low level spells cast often in a short period of time. Maybe make it take a major item to remove the debuff at the highest levels one that takes expensive materials to craft and a long craft time.
Sorcery isn’t very powerful in the game (compared to someone like Thoth-Amon) and if you don’t corrupt your attributes, you can’t use the more powerful spells. I think that the current system, where a dabbler in sorcery can cast a few relatively minor spells and then remove it works pretty well.
I also think that it can be used in a RP way to have it be a slippery slope - because like using drugs, it doesn’t have an immediate permanent negative effect, you keep using it, and more of it, until suddenly you have permanently corrupted attributes.
You don’t need corrupt attributes to cast high level spells. What you do need is higher level corruption levels that could come from any corruption source.
