Each roll gives at most one item: the own loot table comes first, then the common loot of the map (in dungeons, the dungeon loot list comes before them); once the chances add up to 100%, the remaining lines can no longer drop. The player loot bonus multiplies these chances, except at spawn spots with loot without bonus.
