Quick leveling tip

CRAB CAVE

On Serene map u can find a place names Crab cave east of serene city, near the sea.

On the far end of that cave you willl find "Lord black Crab" which is an easier copy of the last boss of the first instance of fishing village.

It can be taken down easily by a level 25 but if a friend of higher level can help you, you can chain it to level very fast. the false-boss will repop 3 second after his death, so that you can chain it very often and fast.

example my vangard lelvel 30 earn 880xp each time, my friend fire mage level 18 earn 1600xp each time, so in ten minutes he can gain a level.
