Well i got a few hints and locations for bosses from Misty to Volcano

first the hints...

1 kill the bosses with a reborn eudemon wich lvll is lower than the pet

2 or a low lvl luck pet

3Dont kill it with xp skill the drop rate is 5% than

4 How higher the lvl boss how better the drops

5 When u see the SpiderQueen kill it as fast as u can but let ur low lvl pet kill it

the spiderqueen is lvl 87......

6 When u are a Mage and u have Invisibility*or something like that)

use it on ou and the boss so nobody sees u and the boss...
