Every row above opens a working tool. The talent calculator and the class pages share one calculator, built on a community read of the beta client, so its trees carry a Reported tag; the race and class tables come from Blizzard. Each class page opens that calculator in place from its red button.
Planning the leveling
Once race, class and talents are settled, the leveling guide covers the level 60 cap, the zone ranges and what Blizzard has not said about experience yet. If you want an in-game route to follow, the RestedXP guide sets out what its Forever guides cover, what they cost and what is still being built.
