Enhance Item

(Epic Level Handbook, page 114, DnD 3.0)

[Item Creation]

You can increase the minimum DC for saving throws of magic items you create.

Prerequisite

Any other item creation feat

Benefit

Choose any item creation feat you already know. When you create an item with that feat, adjust the DC for saving throws required by the magic item, if any, by your key ability modifier.

Special

You can gain this feat multiple times. Each time you take the feat, it applies to a different item creation feat that you already know.

Normal

When a character creates a magic item, she uses the minimum key ability score necessary to imbed a spell of a given level, and the associated modifier to adjust the DC for saving throws, regardless of her actual key ability score, which could be higher.
