The monsters tend to attack, only, those strong enoth to hurt them, they basicly ignore attackers that do 0.00 damage all the time...
Sometimes the monsters are invularunable, ou will not be able to attack them....
I do not know if the monsters become stronger... but, at skill 1 I was able to beat a Karacass (Or whatev it is called), then at skill 3 I tried to kill it and died almost instantly... even thou I stopped attacking and retreated... I died...
I think that EXP, should work differently: You get exp for the time of battle + damage caused to the monster... so no fight would go away with + 0.00 EXP... What do you think?
