Enhance Enchantment

Available to Bard 11+, Magic-User 7+, Mage subclasses 4+, Cleric 9+, and Cleric sub-classes 6+. Spend 500 gp in alchemical oils and three full days working on a piece of equipment of Flawless Construction. Make a Wisdom or Intelligence check at DC 13. If you are an Enchanter also add your Enchanter level. If you succeed, you have enhanced the equipment's existing magical bonus by one point. If a weapon, it now has +2 bonus to both to-hit and damage rolls (+3 if you're an Enchanter). If armor, it yields AC two steps better (three steps if you are an Enchanter) than mundane armor of the same sort. If a shield, it adds a bonus to AC two steps better (three steps better if you are an Enchanter) than a mundane shield of the same type. This item won't rust, pit, fray at the edges, or otherwise show signs of aging. It succeeds on saving throws against destruction if the raw d20 roll is above 2. If you fail the check, you must spend another two days and another 500 gp (1 day and 400 gp if you are an Enchanter) and then make the same check again, with a cumulative +1 bonus. If the item has charges, it's maximum charges increases by two (or by three, if you are an Enchanter). The item is now a candidate for the Superlative Enchantment heroic deed.
