Effect 6 made

[Boop]

Just from looking at the exe, I see a few possible problems.
1:
00446454 > 83F8 06 CMP EAX,6 // (effect 6)
00446457 . 74 09 JE SHORT lf2-char.00446462
00446459 . 83F8 10 CMP EAX,10 // (effect 16)
0044645C .^0F85 349AFEFF JNZ lf2-char.0042FE96 // if not 10, then execute this jmp
00446462 > 8B8CBE 9401000>MOV ECX,DWORD PTR DS:[ESI+EDI*4+194] // if 6 jump here

With this code, the effect will run when the effect is 6, or 16. So you basically replaced effect 16(if it ever existed).




2:
00446495 . 74 13 JE SHORT lf2-char.004464AA
00446497 . C740 70 960000>MOV DWORD PTR DS:[EAX+70],96
0044649E .^E9 F399FEFF JMP lf2-char.0042FE96
004464A3 00 DB 00
004464A4 00 DB 00
004464A5 00 DB 00
004464A6 00 DB 00
004464A7 00 DB 00
004464A8 00 DB 00
004464A9 00 DB 00
004464AA > 8B4C24 0C MOV ECX,DWORD PTR SS:[ESP+C]
004464AE . 0000 ADD BYTE PTR DS:[EAX],AL

You are jumping to line 004464AA, and then you aren't jumping anywhere else. This will cause the exe to crash.

Edit: For your second question, use CMP BYTE [EAX+2FC],1 to check if the HP is one. Then do a JNZ or a JG etc etc.

Example:
00446454 > 83F8 06 CMP EAX,6
00446457 . 74 09 JE SHORT lf2-char.00446462
00446459 . 83F8 10 CMP EAX,10
0044645C .^0F85 349AFEFF JNZ lf2-char.0042FE96
00446462 EB 58 JMP SHORT lf2-char.004464BC

004464BC 80B8 FC020000 >CMP BYTE PTR DS:[EAX+2FC],1
004464C3 ^7F A4 JG SHORT lf2-char.00446469
004464C5 ^E9 CC99FEFF JMP lf2-char.0042FE96

Depending on how much you care about keeping your code clean, you can just do it my way with a jump, or rewrite most of your code .
