Magic Item Rules
Magic items do not require XP.
Create Metamagic feats can be taken by non-magical characters. Spells are still required to create magic items with special effects.
For example, to create a +1 Sword only requires the appropriate craft skills, create Magic Arms & Armor, and the required materials.
To create, a +1 Sword with the flaming option requires a spell to be cast; however, non-magical characters can create a flaming sword by having a scroll of the appropriate type and level. The scroll is consumed during the creation of the magic item although the character need not cast it.
