[Kotohono]

So in MMOs it's common to re-fight, or "farm" a boss for some purpose, usually loot, so let's say a group of players want to re-fight the boss of floor 1 from ep 2, for loot, would this possible?, and if yes is there a limit to how many times players could do this?

Unrelated Question are "rare loot" items, like the cloak Kirito got, do they have special stats not normally found on items, or do they simply offer more stats than other items might offer? Also are such items only available from bosses, or are there chances to find items of that quality at much lower rates on other enemies?
