overhead head chest hands left hand right hand feet left foot right foot
If I missed any, please correct me.
Chest is used for when you want to put wings on a unit. Head is for stuff like helmets while overhead is for stuff like buffs. You can use "hands" or "feet" to put an effect on both or you can assign to individual hands or feet.
I THINK "origin" might be another (for glows and such) but I havent tested it. -VGsatomi
