Yes, sorry, I was trying to speed through the earlier rounds. Fighters at Miyana/Will's level already have a THAQO of 17, and Boudica is very unlikely to fare well against them, or against the caliber of opponents they would be facing.
Regarding identifying magical items; it is different from more recent editions. See the OSE for reference
[ref]; it would take several weeks, and you would have to leave your staff with the guild. Also keep in mind that the guild has the authority to confiscate 'dangerous' magical items, and you will have no legal recourse or anyone to appeal to in such a case. You can still leave the staff with them if you want, but seeing that you are leaving Specularum soon, I can't foresee when (or if) you will ever see it again.
