Level 38 croaker
Loc: 248, 471
Neglectful right arm symbiant, artillery
Hmm, Like his bro' Mesu Ra, that named Croaker often dropps, as the Tormenter of Growth, a special Martial Artist Hat, named "Venomous Coolie", in QL25ish (such a pity for a level 38 mob ...). Unfortunately, this is a pure NODROP item, so, you have to get a team to get the hat at this level ...
By the way, if anyone knows what Croaker or else dropps for higher level (well, my MA is 60 now), let me now please :)
I got ql 46 hat off his brother, drop is fairly rare tho, I have only seen it drop twice, and have killed lots of times.
