Here's another party to try: (my gazillionth game)

Instead of a solo faerie ninja try two faeries to make it a bit easier than solo but harder than most duos. I started one as a ninja (male) and one as a bishop (female). I switched the bish to ninja at lev 15. The only trick I did was to start out with one non-faerie ninja to get the armor. Immediately dropped the non-faerie to make the faerie ninja.

The team is lev 25 and just cleared lower Rapax castle. They are unstoppable at this point, armor levs 34 and 31 before bless (2 fey rings help!), using the Cane and Sword of 4 Winds as main Weapons of Local Destruction. I'll probably finish the game but up to lev 15 or so it was quite a challenge.

I just finished the solo fairy, but in the end it wasn't a solo any more. i made some mistake in the play so resurected the fairy priest amd hired 2 npcso at the end had 2 fairy(ninja 12+/bishop 18, priest30+/thief 1) and 2 rpc.
was dispointed from Cane of Corpo
eli the lich
BTW in the begining 2 fairy stick is very good to train staff the enemy is mostly asllepp
