Modding Spells

[Timbo 17]

I'm trying to edit Burst of/Knight/Master Speed. I used to make SNES romhacks back in the day so I'm pretty good at hex-editng and familiar enough with this that I can make sense of what I'm reading. I've figured out what values I need to edit to make it work but when I opened it in KotOR scripting tool and saved it. I thought I would just be able to edit it directly, save it, and throw it into the override folder, instead it just broke spellcasting.

What am I doing wrong?

 

Here's a sample of what I did to Burst of Speed:

00006234 05 00 00A5 01            ACTION EffectMovementSpeedIncrease(00A5), 01
00006239 01 01 FFFFFFEC 0004      CPDOWNSP FFFFFFEC, 0004
00006241 1B 00 FFFFFFFC           MOVSP FFFFFFFC
00006247 04 03 00002007           CONSTI 00002007
0000624D 04 03 00000000           CONSTI 00000000
00006253 04 03 00000002           CONSTI 00000002
00006259 05 00 0073 03            ACTION EffectACIncrease(0073), 03

If I change these bottom lines like so it should change it from +2 to AC to a -4 in Attack.

00006253 04 03 00000004           CONSTI 00000004
00006259 05 00 01BF 02            ACTION EffectAttackDecrease(01BF), 02

 

Edit: NVM. It's actually way easier than this.
