This may be surprising... But...

[Hessah]

MD's success rate is poor, and it's a stone burner... actually.. the EXP is poor too for lvl 57! so over all its not the best alternative (you waste all ur time only to get a failed KQ)

I suggest you go solo something easier... something in Uruga.. like orcs or hunter orcs for a less busy place... (maybe put a license on ur weapon for extra dmg as well)

Since you're an archer, you should be able to kill the fairly quickly... I always believe that faster kill > slow kill, the exp u get might LOOK less, but i think in the long run, coz you kill faster, u get more exp... plus less stone burning... and less risk of dying

or even solo in PoA? since they hit softer... (and dont pull too many at once!)

Level 57 is the hardest level!! there's tonnes of quest at lvl 58 and most of lvl 59... so... yeah... 57 is a pain in the neck...

good luck!
