Jewels

After returning Sarevok to life I chose not to accept him into the party, so he dimension doored away and the path to the first challenge was still blocked.

I've just finished ToB with both endings, and Nathaniel was missing from the mortal ending. Looking back through my list of saves, the variable was never 2. During chapter 6 I managed to get the extra options when choosing to talk to him, and I had the meeting with Avery in Trademeet, but he was never kidnapped by Bodhi upon entering the Graveyard.

Using DLTCEP to create a spell, I'm attempting to lower the elemental resistances of targets using the same effect opcodes used to increase them, namely 27-30 and 84-85. The problem is that they just don't seem to work; I've tried cumulative, flat value and percentage, and regardless of the type used, target resistances remain the same.

At the moment I've been testing with Permanent (1) timing with resistances 0 and 2*. I can lower magic resistance, magic damage resistance and poison just fine using all three types, but with other resistances (elemental, slashing, crushing, piercing, missile) I'm unable to lower them.

* What exactly do the different resistance flags do? E.g. If a spell effect was to increase fire resistance, what would be the difference between 0-Nonmagical, 1-Dispel/Not bypass resistance, 2-Not dispel/Bypass resistance, and 3-Dispel/Bypass resistance? For that particular case using 2,  I always thought the effect would bypass magic resistance (so it can be bestowed), and could not be dispelled.

I have a custom lower resistance spell which lowers resistance by 30%, and I want to be able to add that to the display text when the spell is cast. At the moment my I simply have SAY NAME1 and SAY NAME2 for the spell name when copying the spell (I haven't bothered with the description as it's an innate ability).
