I'm 90 WHM and have gotten staff to 238 in the Boyhada Tree. However Steelshells are giving me practically no skill ups anymore, even with the foods. I've seen the guides on wiki and some posts on here that suggests the Druriumshell in Vunkerl Inlet (S) are good since they are level 90-95; but won't these pulverise me solo? My skill works out at about level 77 (C+) so won't those be a bit high anyway? I'm not really interested in joining a group that will just want me to spam cures and haste 24/7 instead of attacking.
If all else fails I could always level up my MNK or PLD from 75 to 90 and level Staff with one of them, although that sounds a bit drastic.
Any Suggestions?
