There's a large variety of different types of items in the bot currently: Healing Items, Battle Items, Consumable (Skill) Items, +Stat Items, Summon Items, Shop Level Reducing Items, Gems, Keys, Accessories, Portal Items and Misc (Crafting) items. Here's a few examples of each.
Most of these will restore a fraction of the target's maximum HP. If used with Fullbring, they will restore a fixed amount instead.

These items, when used, will increase your stats or orbs by a certain amount. You cannot buy these items in the shop and must be found by defeating bosses and being the most stylish. None of these items can be used with Fullbring.
To keep a little bit of mystery with these items, I'll list some of them but won't say what they do. If you want to know, get out there and defeat the bosses and be stylish about it.
