Thank you for the explanation on how the file format worked. I removed 2 skills from Ena and added 2 skills to Eddie. I had to shift all the blocks in between the edited sections and had to manually recalculate all the pointers in the section (mentioned in Step 3 of your guide).
I got many errors at first, but suddenly recalled to use compression LZ77 Type 10 instead of Type 11. Then it worked swimmingly.
Heya, your 010 template was a tremendous help. I was about to learn and make it myself until I spotted it a few pages back. Thanks.
I would've assumed ashera has a skill that prevents everyone but Ike from dealing the finishing blow... in either her character block or her class block. However, after taking a look, I do not spot any skill that would indicate such an effect.
-SID_FINALBOSS -SID_MANTLE -SID_MIDDLE (no idea) -SID_HIGHEST (indicate final class tier)
I did spot SID_IMMORTAL in the entire pool of skill strings. I guess you can try renaming/replacing it with a useless skill and see if it works.
