I do not see the boost in caster level reflected when casting spells, and the +1 to ability scores is counted as a non-stacking Enchantment. Meaning that if you have any skills already enchanted by an item there is no benefit at all. IMHO this entire passive is completely borked.

Glitter of Fame: (Passive) Gain +1 to your effective Arcane caster level and a +1 to hit. Special Effect: As long as you are above 10% Health, you radiate confidence: gain a +1 to all Ability scores.
