Talent Sequence is an addon for World of Warcraft Classic that adds the ability to import talents by level from Wowhead's Classic Talent Calculator. It also includes accommodations for the Talented addon.

Check out a video demo importing a talent build here: https://youtu.be/XRenWZdJvBM

To use the Talent Sequence addon, you must have a URL from Wowhead's Classic Talent Calculator and have the Talent Order section expanded(see below).

To Import a new sequence, open the Talents panel (default key: N) and press the "Talent Sequence >>" at the top or top right(Talented Addon).

In the pop-out frame, press the "Load" button at the bottom.

In the pop-up Talent Sequences window, press the "Import" button at the top right.

In the next pop-up, enter a Name for your build, then paste your Wowhead URL in the pop-up after.

Different warnings or failures may appear depending on your name or pasted URL. Examples below:

Successfully importing a sequence for a class that is not the current character's class will be met with a success message.

Clicking the name of the build you want to load will load it into the Sequence frame display next to the Talents UI.

Clicking the cogwheel will allow you to rename the sequence. Press the Enter key after typing the new name to save it.

Holding Shift and clicking the general prohibition sign will delete the sequence.

If using the Talented addon, the sequence list displays properly to the right of the new window and the Toggle button in the upper right.

Much thanks to /u/mrdarkey and /u/lentus for helping me test and debug the addon in the Classic Beta!
