Those bigger monsters, or well mods as they like to call them here? lol i dunno, give decent loot...
but if you find a area where they spawn like 5 or 6 medium monsters that give about 300 gold each...
you can get more gold killing them, in the same time frame it would take to kill One big dragon or harder monster...
thats my method to save money and resources on mana/manapots scrolls, all that crap, just get some good armor weapon and tackle some medium monsters over and over, that respawn fast, and you can rake in alot more gold in a shorter amount of time, rather then spending that same amount of time on one big guy...
this make sense im drunk, but im sure you get the point
and if you find a treasure map throw it away, they are worthless and a waste of time, not worth the effort
( which is hopefully adjusted and tweaked soon )
