I just thought of a video game mechanic that I'm sure has been thought of, but I've never seen:

You basically level your character's ability with common commodities in the world. You learn how to cast fireball with sage, and recall with sage, and speed with sage, but like you can only cast teleport with a bat's wing, and if you get better with bat's wing magic, you can eventually teleport other people and spells and shit. In an MMORPG, that itemspell class's power would be measured by the free market.

Usually items are recipes for spells and shit in games, but you don't necessarily become an expert with certain plants or items or shit. I want to see wizards become experts with sage and parsley and shit.

Blizzard plz.
