Respec

Respec is an MMO term that means respecifying part or all of your character's current build.

In DDO you can respec:
 * enhancements by talking to your class trainer
 * This requires a gold payment that increases with your level and can only be done once every three days. All your enhancements are reset each time, including all Prestige Enhancements.


 * spells (for Bards, Favored Souls, and Sorcerers) by talking to your class trainer
 * This also requires a payment of gold that increases with your level and can only be done once every three days. Each spell respec allows only a single swap.


 * feats by talking to Fred
 * This requires a gold and Dragonshard payment, detailed below. Only one feat can be respecced every three days.

As of Update 3, it is not possible to respec your race or alignment.
 * skills, stats, classes by lesser/greater reincarnation


 * * True Reincarnation - You lose all XP, quest flags, raid completions, favor, and tomes used. This is closer to remaking the character from scratch than respeccing.

Costs to Respec a feat
The Hall of the Mark quest given by Lockania in the Marketplace provides a free feat respec token once per character. Beyond that, both gold and a Dragonshard are required, with the amount and type depending on the current character level.
