pavlekocev25: Thanks TwoHandedSword,
I tried a few things:
1. Unfortunately Resist Magick doesn't stack, it goes to MR 50 with the 1st casting and goes back to MR 0 with the 2nd, I also tried to combine Resist Magick (MR 50) with Dorian's Amulet (MR 30~40) but to my surprise my MR was still 50, I read somewhere 2 guys mentioning that Resist Magick caps at 50, is this really true?
Can you give me some advice how to reach MR 95 and which items increase MR?
2. A bit in another direction, but I wanted to test if TA 100 can protect from Disintegrate; I had MA 25 and Sebastian had TA 99 and when I cast Disintegrate on him he dies every time; if I have TA 38 or more Nasrudin never casts Disintegrate on me; is there someone else who might try to cast Disintegrate on me if I have TA 100? I read 1 guy saying that TA 100 doesn't protect from Disintegrate, but I wanted to test this properly if it's really true.
3. Is it possible to find a Scroll of Dweomer Shield somewhere? Maybe some Magick Shop Clerk sells it?
1. Whoops; I guess that spell isn't designed to stack after all. I had thought it had scaled, depending on the MA of the caster; looks like I was wrong.
1a. Achieving a MR of 95 (the true maximum)
is possible. I have an elven PC who has done so, by way of a Dorian's Amulet, Arcane Leather* and an Arcane Ring (and the 100 MA needed for them to have full effect) and the +30 MR bonus which is part of the successful completion of the Arcanum Gods Quest.
*Arcane Robes would offer a larger potential bonus (up to +50) at the cost of a much lower AC and DR; not even close to a fair tradeoff, IMO.
2. There are some spells that don't check against MR. Teleportation is one; based on your experiment, Disintegrate is apparently another.
3. According to the OSG, nobody stocks a scroll of Dweomer Shield — which also makes it extremely unlikely that you would ever find one as treasure, either. On the plus side, however: if you ever did, any of the magick shop clerks would be delighted to take it off your hands.
