Why are leprechauns a good source of mesos?

With less than 5000 total hp, and meso drops that can exceed 2000 mesos, they have by far the best meso drops in the game.

Also, they're stationary so there's no real danger of touch damage unless you stand on them.


In comparison, Nightshadows have 70000 hp and drop 1100 or less mesos. And a lot of level 80+ monsters do not drop over 1000 ever.
