Soulstone

Soulstones are an item in which you can store a single skill, then later transfer that skill to another character on your account.

Currently they are available in green (from the Samurai Empire Expansion) and in blue. A red Soulstone is available as first year veteran reward choice (though not as token and thus cannot be traded to another account).

While these Soulstones have an unlimited number of uses, there also exist Soulstone Fragments which have only 5 charges when fully charged.

You may only use a soulstone bound to your account in a safe log out location such as an inn or house that you own or are accessed to. You must wait a certain amount of time after leaving combat to use a stone and you may only use a stone once per 24 hours. Using the stone means storing and then claiming a skill from it or storing and then removing a skill by flushing it from the ston without absorbing it to a character. The 24 hour timer does not start however until you claim the skill so if you stare a skill and claim it the next day you must wait 24 hours before storing again.

You may not claim a stored skill if it exceeds your skill cap.
