This is more a thread for collecting my ideas as I start work on the crafting system to replace the WotC one in Arhosa.
Must be fairly fast to craft, so that it can be accomplished in normal campaign time, rather than requiring months of downtime.
Does not cost XP.
Must not require spells to craft, especially since there are so many different systems with their own magic items lying around.
Must not severely impede the build of a character.
Because Arhosa is a low magic world, magic items should be expensive.
The result of all of this is that there shouldn't be any feat cost for the system, and at most 1 or 2 skills required (probably some variant of Craft). Which would end up with it looking something like Spellsong, with certain levels of bonus gated by X skillpoints invested into the system...
