Cocklefighting

Finding one

Magic items cannot be bought. On a rewarded win you have a 1% base chance to dig a fresh one out of the pit floor (scaled 0.5x to 2x by the level gap, up for punching up), drawn by rarity weight from everything your opponent’s level has unlocked. Separately, every fight rolls a steal: a beaten rival’s carried item changes hands at 1% when un-upgraded, decaying toward a 0% floor with a 4-level half-life as its owner invests. You hold at most one of each item.

Losing works the same way in reverse: lose a fight and each item you carry runs that same steal risk. A plundered item is gone for good, and its levels go with it; the thief receives it un-upgraded.

Empowering at the Hollow Grotto

Each upgrade level adds 40% of the item’s BASE effect to every bonus it grants; a cursed drawback eases far more slowly, on a 15%-per-level curve, so a curse never washes out. Fixed traits (pierce, omni-element, affliction amplifiers) never scale. Each level costs 1.25x the last, from a base set by rarity:

Rarer items are born mightier and cap lower, so every rarity’s maxed power lands in a comparable band and the humble rare is the one piece a dedicated cockle can push all the way to 30. Upgrades also harden an item against theft, per the steal decay above.

The catalogue

All 28 uniques. Weight is the relative draw chance within a find; min level gates an item behind opponents of that depth. Effects are shown at level 0, exactly as the engine generates them.
