Are there random affixes? Are there levels or rarity? Can they be customized in any way? when in a group how are they distributed? Is it whoever grabs them first, or individual loot for each person, or doing random rolls for it?

Gear items can be enhanced (IE+1, +2, +3 etc) some gear has special abilities that activate at a certain enhancement level, for example a pair of boots might have +3% movement speed at +9, +3 balance at +6 and +1 balance at +3

Weapons and chest armor pieces also have slots for gems. Gems can have a wide variety of effects, from + damage against normal monsters, + damage versus boss monsters, attack speed, critical hit chances, etc etc. Armor upgrades can be anything from reduced damage to more balance.

Some randomly dropped gear will be unidentified. this gear must be identified with a special item to be worn and to uncover what kind of effects are on the gear. higher rarity items need better identification scrolls to be wearable.

I haven't messed with grouping at all, so that will be something someone else will have to answer, but I would assume it's the usual "distribution in order except for items above X quality, which have to be rolled for, while gold is split evenly" that is the standard in most MMOs

Thanks for the information. Sounds fun.
