How to use WeiDU to edit Carsomyr?

Lathspellguest

Basically, I want to change the MR from 50% to 20%, remove the additional damage to chaotic evil, remove the "dispel magic 3x per day," make it usable only by wizard slayers, and also rename the sword and change the description.

Or is it easier to create a new +5 two-handed sword that dispels on hit and provides 20% magic, and then replace Carsomyr in Firkraag's drop?

In either case, I have no idear how to use WeiDU to accomplish my goals. I can make the appropriate changes in Near Infinity, but they're undone by mod installs after the fact.

While I wouldn't mind seeing how to do that easily - it would be easier if you just did your Near Infinity edits after modding? It's not like you'll be doing it more than once per playthrough. And than keep your edited Carsomyr file in a safe location and just copy it to override when you do another installation...

Actually that probably is the easiest way to do it. In that case, I'd just need to know how to have WeiDU replace the description text, right?

The following has been tested only on BG2, because I don't have BGII:EE, so it is possible that some changes may be required, but it should get you started.

First you need to create a tp2 file containing something like:

BACKUP ~Your_mod_name/backup~
AUTHOR ~Lathspellguest, at http://forum.baldursgate.com~
VERSION ~v1~

BEGIN ~Your mod~

COPY_EXISTING ~SW2H10.ITM~ ~override~ // Carsomyr +5
  PATCH_IF SOURCE_SIZE > 0x71 BEGIN
    // here we use patch functions and/or macros
  END
BUT_ONLY_IF_IT_CHANGES

then you can modify the Carsomyr. Check WeiDU documentation for more info, but basically that's what you need to do:

Alternatively, you can create a new item by modifying the original Carsomyr with NI. Let's say it's called MYCARS.ITM, then you can replace in Firkraag inventory with

BACKUP ~Your_mod_name/backup~
AUTHOR ~Lathspellguest, at http://forum.baldursgate.com~
VERSION ~v1~

BEGIN ~Your mod~

COPY ~Your_mod_name\items\MYCARS.ITM~ ~override~
  PATCH_IF SOURCE_SIZE > 0x71 BEGIN
    SAY NAME2 ~write here the new name~
    SAY IDENTIFIED_DESC ~write here the new description~
  END
BUT_ONLY_IF_IT_CHANGES

COPY_EXISTING ~FIRKRA02.CRE~ ~override~
  PATCH_IF SOURCE_SIZE > 0x2c8 BEGIN
    	REPLACE_CRE_ITEM MYCARS #0 #0 #0 ~NONE~ ~QITEM2~
  END

@subtledoctor Awesome! That's exactly what I was looking for. Thanks so much.

In any case, for local modding no weidu is required, you could just as well do everything in NI, modify the effects, add new lines to dialog.tlk and reference them in the .itm file.

Some say NI dialog.tlk editing is unstable but I've never had any issue with it

It's actually quite unstable, depending on what you do. WeiDU is the only safe way to edit the dialog.tlk.
