Question about maps

Hi, i want to ask if maps drop from level 58 or 59 monsters or not. Also, what is the best way to find them ?

I wonder how there are people who sell a lot of maps at low costs, how do they find so much ?

The lowest level zone I've found a map in is level 60. Not sure if it's possible to get a map drop from a blue mob in a L59 zone (as they are +1 level) or a rare mob in a L58 zone (they are +2 levels).

Your character's increased item quantity does not effect map drops, so the best way to get map drops outside of maps is to kill lots and lots of mobs as fast as possible in a L60+ zone. The best place to get map drops is in maps as the increased quantity on the map itself DOES effect map drop rates.

As for map sellers, these are likely high level characters who run lots of high level maps. For these players running level 66-68 maps results in not enough exp for the time invested, so they just sell off all the low level maps that drop and keep the high level ones.

Maps drop from lvl 60 and higher monsters.
Magic monsters in a lvl 59 zone are lvl 60 (and rares are 61).
Rare monsters in a lvl 58 zone are lvl 60.

Best to stay in lvl 60+ zones for optimum map drops.
