Dualspec
Dualspec is now available on Moonwell x100. Book of Talents allows you to quickly switch between talent templates (specs) that you select in advance. When you change the spec, all your current talents and panel spell positions are saved to active spec, which you can switch to in future. If spec you switch to already has a saved template, it will be restored instead of current one. You can navigate between specs by the number of talent invested. In fact, this is not a dualspec, but a triplespec. Considering that TBC has 3 talent trees, we made it possible to save specs in 3 slots.
Book of Talents can be purchased for free from the new vendor Anriann in Shattrath City, and is given out to all new players upon character creation.
