World drop
From ThresholdRPG Wiki
The world drop system is a mechanism by which random loot drops off kills no matter where you are in the game. The loot could be potions, magical scrolls, Battle cards, all sorts of different rewards.
These drops are in addition to what may drop from a monster's loot table, or a specific region's Zone drop table.
Drop rules
There are a few rules governing how drops will be awarded.
- World drops will not drop off critters
