retrogames: Thanks a lot. I do have one ring of sanity, but am I right in thinking that it can only be used on one affected party member for each combat round? BTW, I think it's got 4 charges. Can you recharge them?
Regarding the magic screen. Vi is able to cast this spell, but I only had it on level 4. I just tried level 7, and it worked, despite the level 7 circle not being green. (I guess I could reload, if the spell fizzled.)
When you have run out (or low) of mana, what do you tend to do? Camp, or drink some magic nectar? I'm reluctant to camp, because I'm worried that this will simply generate more spawned monsters to fight, kind of defeating the purpose behind camping, as you will then use mana for those battles! The same question goes for running out or low on HPs. Do you camp, or drink health restoring potions?
So with the magic screen set to 7, should I run up to the group and use melee combat, or perhaps maintain some distance (but not too far), and pick them off with ranged attack, including some spells perhaps?
Also, Vi has a spell called Soul Shield, and someone else has a spell called Silence. Would any of these be useful against these monsters?
Thanks for any further advice! :)
The Ring of Sanity can indeed only be used on one character per round, but that might still be enough.
You can recharge items by selling them to a store and buying them back. (Also, I believe this particular item is buyable in a shop, so you can get more if needed.) The only items you *can't* recharge are those that can't be sold anywhere, and I can only think of one item like that at the moment (which doubles as a key item, and is hence marked undroppable).
Soul Shield will raise your party's Mental (and Divine) resistance, which *should* help against the Turncoat effect. (The drawback of this spell is that it takes a round to cast and it wears off when the battle ends.) Silence will not prevent their turncoat attack, but it will prevent the enemies from casting any actual spells they can use.
If your party is melee oriented, it is probably best to get into melee combat and hope for the best.
