[Titanium]

1) [BASETYPE] is the main category of the item, its values can only be Weapon, Armor, Jewelry, Socketable, CraftingReagent, Utility.
[TYPE] is a more specific category of the item, e.g. Axe, Wand, FistWeapon, Shoulder, Chest, Cloak. (You can refer to the existing rules for more examples)

2) && means "and".
3) || means "or".
4)
[QUALITY] == "Rare" && [BASETYPE] == "Weapon" && [ONEHAND] == True # [DPS] > 1000 && ([CRITDMG%] > 0 || [LOH] > 700) && [SOCKETS] > 0 -> [KEEP]

means the bot will look at the item. If its quality is RARE, and it is weapon, and it is one hand, then the bot will further look at its detail stats.
Its DPS must be above 1000. Either its critical damage % is greater than 0 or its Life on hit is greater than 700. It should have at at least 1 socket. If the item matches all these criteria then the bot will keep the item in stash.
