Woodworker: Improvement in TESO

The Woodworking Station lets you Improve wooden items in The Elder Scrolls Online

To improve an item, select the category you wish to improve—weapons or shields—in the upper right corner of the improvement menu. A list of the items in your inventory that can be improved will appear.

Double-click on the item you wish to improve and it will appear in the "Improve" slot in the center of the screen. The resin needed to improve the selected item's quality will appear beside it. Click the "plus" button beneath it to increase the amount of tempers, which will increase the chance that the improvement will be successful. When you are satisfied press [R] to commit the improvement.
