Respec

Respec is an MMO term that means changing ("respecifying") part or all of a character's current build.

In DDO it is possible to respec:
 * Enhancements via the Enhancement Tree display.
 * Enhancements can be reset using Currency or Astral Shards while in a public area. The platinum cost is determined by the number of action points currently spent, as well as a multiplier determined by the number of enhancement resets that have been done recently
 * When resetting enhancements, all enhancements can be reset at once or enhancement trees can be reset individually
 * Spells (for Bards, Favored Souls, Sorcerers, and Warlocks) by talking to the relevant class trainer
 * This requires a Currency payment that increases with level and can only be done once every three days
 * Each spell respec allows only a single swap, unless the character uses Blood of Dragons
 * Feats by talking to Fred
 * This requires payment with either gold and Dragonshard or Astral Shards, detailed here. Once per life a feat swap can be done for free by completing the Hall of the Mark quest from Lockania. Only one feat can be respecced every three days.
 * Skills, stats, classes (including all class abilities) by Lesser/Epic Reincarnation (LR/ER)
 * Prior to Update 20, respec could also be undertaken by Greater Reincarnation, but this functionality was rolled into Lesser Reincarnation
 * Alignment by DDO Store item
 * Race and Gender through True Reincarnation (Heroic (HR), Iconic (IR) and Racial (RR) Reincarnations)
 * Prior to Update 20 race, but not gender, could be changed via a True Reincarnation


 * * Build Point Upgrade: Going from 28 to 32 point builds via Lesser or Epic Reincarnation requires the 32-point build option to be unlocked (either through 1750 favor on a per-server basis or purchased from the DDO Store for 1,495 DDO Points)
 * ** Epic Reincarnation: Acts as a Lesser Reincarnation with the added bonus of going from Level 30 to Level 20.
 * *** Forms of True Reincarnation: Character loses all XP, quest flags, raid completions and favor. This is closer to remaking the character from scratch than respeccing.
