I checked the manual, but couldn't find anything regarding "unsilencing" a silenced party member. Are there any items in the Wizardry world that might help? (I'm guessing that there isn't a spell available to do this job.)

Restoration can cure *any* negative status ailment except for death or draining; this includes silence. This spell is available in potion form, which can be an option here, and is notable because being silenced doesn't prevent its use. There is also a musical instrument that casts this spell (though it can't be used while silenced and it requires level 18).

Allowing a character to die will remove all other negative status ailments; when revived, the character will no longer be silenced. (You can actually cure draining without a Renewal potion this way.)

Also, note that Bishops don't completely lose their spellcasting when silenced; they can still use Alchemy spells (and said spells count as Alchemy in that situation even if another spellbook skill is higher). One of my favorite things to do when my Bishop is silenced is to have her cast spells anyway.

Gadgets can be used while silenced as well. Instruments can't, however.

Thanks! :) I suppose if either my ranger or ninja get silenced, it won't affect any of their spellcasting abilities, as these two professions both study from the alchemist spellbook.

Earlier on in the game, my monk died, and I brought him back to life using a potion. Are dead members resurrected "penalty-free", or do they suffer in any way from this process? I think I read somewhere (not in the manual) that they lose one vitality point. If that's true, is there a way to restore that lost vitality point somehow? Thanks a lot.

In Wizardry 8, there's no such penalty.

In earlier Wizardry games, there is such a penalty (though not always; it's actually a little complicated), but there's no practical limit on level advancement in the earlier Wizardries. (Wizardry 4 excluded, but since you only have one regular party member whose death causes game over, this whole point is moot.)

Perhaps you read something about an earlier Wizardry game and thought it referred to Wizardry 8.

By the way, in earlier Wizardry games, if a level up or resurrection effect would lower the character's Vitality below 3, the character's condition is changed to LOST, which is very hard (maybe impossible in some Wizardries) to cure, and which causes the character to be deleted on return to town.

Yep must have been!

"Cure lesser Condition" should do the job. Either by spell or potion.
Good luck and have fun

I right clicked on the Cure Lesser Condition spell, and it says that it can assist with fear, sleep, blindness, nausea or irratation. Unfortunately, it didn't list Silenced as an ailment that it can help resolve.

BTW, I got Vi to cast her learnt Cure Disease spell, and although it didn't fizzle or backfire when cast (it appeared to "work", as an animation was displayed on the spell's recipient avatar), it didn't cure the disease, because the recipient avatar still displayed the diseased icon. If this occurs, has it partially cured the disease (perhaps lessening its advancement), or has it not worked at all? Thanks.

(Edit: just fixed very minor typo.)

I don't know, but you could experiment. Cast the spell, rest to get Vi's spell points back, then cast it again, and repeat.

Alternatively, cast the spell, use Magic Nectar (or Mana Stones, if you have any), and cast the spell again, and see if it eventually cures the disease.

(Remember that, if it doesn't work (and you aren't playing Iron Man), you can just reload if things don't work out.

Anyway, the methods I mentioned for curing silence in the earlier post (Restoration or death+Resurrection) should work for disease, and for some reason Restoration potions are cheaper than Cure Disease potions.

@dtgreene, I experimented as you suggested, and got these consistent results (using an old save file, with the ninja having picked up a disease in a fight.)

If Vi casts Cure Disease at power level 2, it works (it doesn't fizzle or backfire), but takes 3 of these casts to rid the ninja of disease.

If Vi casts at power level 3, when it works (the power cast circle for level 3 isn't green), it takes just 1 working cast to rid the disease.

(What I haven't done yet is to use power level 2, and cast the spell say twice, then wait to see if the disease eventually goes away, although I very much doubt this.)
