The unique identifier for the loottable
This is not used in the server any place; it's just there to make the database more human-readable. Usually the loottable name is the same as the name of the npc with the loottable, but it doesn't have to be.
The minimum about of cash the mob will drop when killed. An entry of "1" would set 1 copper as the minimum cash drop. An entry of "54321" would set 54 plat, 3 gold, 2 silver, 1 copper as the minimum cash drop. As far as I know, there currently is no way to make a mob drop more than 9 copper, silver, or gold at a time.
The maximum amount of cash the mob will drop when killed. The format is the same as for mincash. When the mob spawns, the server generates a random value between the mincash and maxcash, and the random value is assigned to the mob's loot.
No one seems to know what this field does, and there are actually 0 loottables in the ProjectEQ
database that use this field. Leave it set to 0 if you want a normal "pick an amount between mincash and maxcash" cash drop for your mob, as changing it from 0 will cause erratic results.
