RChu1982: I'm pretty sure that most weapons and armor that use the last charges don't disappear, though I hear that Mana Stones will disappear completely if the last charge is used. Is this true? Mana Stones start with 3 charges, and if I use the 3rd charge, it will just disappear? I'm too afraid to try it. If this is true, then Mana Stones only can effectively get 2 uses.
If an item is equipable, it will not disappear when it runs out of charges, and it can be sold and re-bought to recharge it, provided that the item doesn't have the Quest Item flag. (If it does, then there's no way to recharge it, but the one case I can think of (the FlameQuencher Wand) will disappear anyway once you use it where it needs to be used.)
If an item is *not* equipable, then it will disappear when it runs out of charges; this includes not just Mana Stones, but things like Duct Tape. Furthermore, if that last use comes from non-combat use of the "use last item" shortcut, the game may crash with an assertion.
With Mana Stones, that does mean that, if you intend to recharge them, they effectively get only 2 uses between charges. However, if you *don't* intend to recharge them, you can use them 3 times, and (as long as Crock is still alive) they can be bought for cheap, having the same base price as Magic Nectar. Assuming that the success rate of Mana Stones is higher than 1/3 (a reasonable assumption, given how Artifacts will get some points automatically through normal play and how low the skill required for 100% success rate is), buying Mana Stones and using them is more cost-effective than buying Magic Nectar and using it. (With that said, note that, particularly after going through Rapax territories, you will likely have more Magic Nectar than you'll probably ever need.)
Also, you mention you're too afraid to try it, but why not just save first, try what you want to try, then reload afterwords? (This is assuming you aren't playing Ironman, of course.)
From what I've read, there's a way to make a character completely immune to physical damage, at which point the character is apparently also immune to status from physical attacks.
Requirements, from my understanding, are as follows:
* Must be a Dwarf or a Monk. (I recommend Dwarf here, as Monk's stealth makes them less likely to be targeted, which is not desirable for this setup.)
* Must have Iron Skin unlocked, meaning 100 base Vitality, and have a high score in that skill. (Worth noting that there's a Bard only piece of equipment that boosts this skill.)
* Someone in the party must have the Body of Stone spell (which means the character must have Alchemy). Furthermore, that same character must have high Power Cast.
* Cast Body of Stone on the character in question, and that character will become invincible, at least against physical attacks, until the spell wears off. Who needs Guardian Angel at this point?
Another use of Body of Stone is via the Granite Potion, which apparently Burz sells. If you're having trouble with Gregor, drinking this potion might make the fight easier.
