DN Sea Leveling Bug

I heard somewhere that there is a bug in leveling up. Someone told me it's in Foothills of black mountain. Anyone know's how to do it? Or any bug about leveling up? i want to make new characters.

I guess they wont share it... but yeah I see random people lvl so fast there from 26 till 50 less than 5 hour... kinda imposible hahaha

Really!?!How?can anyone share it

i'd prolly go for legit training. i tried 26 to 50 in less than a day too. master - app method
