I never said anything about memorizing spells, as it would be a little too slow for a faster game like ToME, but maybe it wouldn't be the worst idea to have mana to cast spells quickly and be able to use mana to 'memorize' it for later.
And before you get outraged, remember that something similar is already being implimented in ToME, with the Spellbinder spell.
I don't get why everyone is getting upset about anything like not ever wanting to play the game again if so-and-so happens. If anything I think of ever gets added, it will probably be in the form of a mod. And even if it gets added to the main game, and if someone neglects to make it possible to perfectly enjoy every previous aspect of the game, then there will surely be a few people like you that would want it out, and they will make a mod that will remove it.
I don't know about everyone here, but I can't really think the greatest when being negative. If saw a mod around here somewhere that sounded bad, and I said "No, that can't do and wouldn't be fun at all," then I wouldn't really get anything out of it. But if I thought about some of the interesting strategies, character builds, loopholes, fun parts, etc. for a while then I would be filled with ideas about everything from pick-up lines, to get-well soon cards, to what to have for dinner, to new ideas for characters, to what to do in a battle with a certain unique, and all the way to plans to take over the world. So try not to say that Gandalf didn't memorize spells, because the reason he didn't use magic so much was because he decided to sleep in mornings and knocked off one of those two hours.
Besides, if you could memorize enough spells, then you wouldn't need to carry around spellbooks, duh Tabris.
... But does damage increase spell failure on monsters? Nooooo, that would be evil, Sonny G, monsters don't ever fail their spells, all monsters have perfected the arcane arts automatically and can use magical items and special abilities by some unholy alliance with Morgoth or something. Don't ever question your superiors, Sonny G, that is MORGOTH talking through you, Sonny G! Don't you dare fall down the path to the dark side, Sonny G!
....
But I digress.
