Loot
One drop a minute. Luck decides what.
Items are not a per-kill lottery. The clock deals one every minute or so, twice as often while you are still small. Luck barely changes how many; it changes how good. Bosses drop two rares. Vaults hide one behind a key.
Eleven slots: weapon, shield, helm, shoulders, armor, belt, legs, boots, two rings, an amulet. Every base carries a signature stat of its own; the ladder of bases marches with your level, so a Leather Cap retires when the Kabuto shows up.
Item level is your level, give or take three. You cannot wear what is above you; it waits in the bag. Magic and better roll +N to a skill of your class; legendaries always do.
One unique per skill. A Pyre Wand is strong on its own; with Fire Bolt at rank 9 it fires three bolts in a spread. Sunstone makes Fire Ball leave burning ground. The rest empower their skill outright.
