Yes, I am fully aware of the infinite amount of magic threads. You don't need to tell me.But after seeing this nifty little game called
Magicmaker, I got inspired.
This is not a blatant rip-off, but some correlations between Magicmaker and this suggestion are to be seen.
This could also contain bits of alchemy, too.
There could be two/three ways of obtaining the power to use magical powers.
Deity gifts. Deities and gods could bless a handful of their followers with randomly-generated spells (within reason) that they could pass down onto their apprentices. Said spells would be more or less related to the deity's sphere(s). (this would also mean an extra skill related to magic, like Wizard/Sorcerer/Mage/whatever)
Spellcrafting. Using gems, magical workshops, and various extracts and other miscellanea, one could create random (again, still reasonable) spells...Or die trying. They could be also "enchanted" onto the gems (the better the quality of the gem, less likely the spell is going to explode in your face, so those perfect gems could finally become useful), which could be attached onto weapons (decorations) to give them the effects of the spell(s) within. (various HFS parts could be used to create spells as well, so syndrome-inducing spells are perfectly plausible)
You could enchant items other than gems, but effects might be less than ideal.
Most spells will not summon fire-breathing winged hydras, though (but a legendary spellcrafter wizard might make one, if the beasts doesn't burn him to a crisp afterwards) - so a *<<bone spear>>* enchanted with "Twindabbles the Waters of Spinning", which is actually a spell that generates a pool of water at the target location (equivalent to dumping a bucket, but without any buckets or water involved) might not be terribly useful unless you're somewhere where water is valuable (like a desert or some saltwater-heavy area).
Learning from books. Secrets of Life and Death style, mages could write down secrets of magic in books, to let aspiring mages learn from them in the future, whenever that may be.
Learning from other wizards. Powerful mages that have entire spellbooks can build towers/academies/keeps in which they gather their apprentices to pass down their power from generation to generation.
When creating (or casting) a spell, a mage in question may and will fail to cast it properly many times, and effects may range from nothing happening to misplacement to magma forming in his lungs.
While I don't necessarily think mana would be involved, casting multiple spells in a succession is probably not a good idea...
So while you flame me for making another magic thread, please at least tell me whether or not this is a good idea.
