_Custom Item Slots - Eniripsa96/SkillAPI GitHub Wiki
Items that can count towards attributes and can use requirement can be specified in the configuration by their slot number. This can allow you to have slots other than armor/held items to give bonuses.
Open up the config.yml, find the "Items" section, and then change the "slots" option to those you want to use. What various numbers correspond to are described in the config.yml and are:
- 0-8 = hot bar (left is 0, right is 8)
- 9-35 = main inventory (top left is 9, bottom right is 35)
- 36 = boots
- 37 = leggings
- 38 = chestplate
- 39 = helmet
- 40 = off hand
For a full list of what can affect the defined slots, see the Items page
