You can create items using the knowledge gained from all of your spellcasting classes.
Prerequisite: Any item creation feat, able to cast spells from two different spell lists.
Benefit: When acquiring item creation feats or when creating magic items, you can add together the caster levels of all your spellcasting classes to determine your caster level. For example, a 1st-level bard/1st-level cleric/3rd-level wizard could gain Craft Wand and create magic items as a 5th-level caster.
Energy: Solar / Sun 
Manipulation: Blast – 50’r 
Strength: Plasmic 
Caster Level Required: 27
Craft Wand - caster level × the spell level × 750 gp
CL (28) x SL (14) x 750 gp = 294k gp [Bronze Cubes]
Caster Level (CL): The next item in a notational entry gives the caster level of the item, indicating its relative power. The caster level determines the item’s saving throw bonus, as well as range or other level-dependent aspects of the powers of the item (if variable). It also determines the level that must be contended with should the item come under the effect of a dispel magic spell or similar situation.
For potions, scrolls, and wands, the creator can set the caster level of an item at any number high enough to cast the stored spell but not higher than her own caster level. For other magic items, the caster level is determined by the item itself.
So for non-epic magic items it looks like a enhancement bonus on a skill check cannot be greater than +30.
Skill Bonus (Competence) = Bonus squared x 100 gp (similar cloak of elvenkind)
Ring of Spellcraft +30; 90,000 gp
Ring of Knowledge (Arcana) +30; 90,000 gp
