Path of Exile · Respecialization
Passive skill refunds
Refund points allow allocated passive skills to be removed, with the source describing item, quest, and NPC respecialization methods.
How it works
The source says skill refund points come from Orbs of Regret and quest rewards, and that the Respecialisation option using Gold is available via NPCs. It lists up to 20 refund points from quests. The passage does not give a gold cost or establish the terms for a full-tree refund, so those details are not stated here.
