The TBC Classic talent/equipment simulator

Nine classes, three trees each, read from the game client's own tables, and the gear to wear with them. Set a build, dress it, share it as a link, and press Simulate to see what the points and the equipment are worth in damage.

Pick a class and spend the points — one a level from 10 to 70, so 61 of them, with a tree's next row opening at five points in that tree. Start from a card for any phase and spec, or from nothing. Choose a race the class can be, then set every slot: the item, its sockets and gems, its enchant, with the set bonuses and the character's own stats shown as you go. Simulate runs the build on wowsims' combat engine, and Compare with sets it beside another build in that build's own gear, so the difference you read is the one you changed. The whole build rides in the address, so copying it shares exactly what is on screen.
