Monster Hunter Rise - Monsters Hp modifier

[SilverRabbit90]

I tried to create a cheat to change the monster HP in Monster Hunter Rise.
The code works partially.

I found the monster life code, trying to search in 8Bytes and doing Changed/Unchanged Valuse (with Decreased/Unchanged values it doesn't work, for some reason -.-)

This is the information to access from the Memory View:

array:
41 89 4B 18 83 E1 03 41
INJECTION POINT:
MonsterHunterRise.exe+3B5C67C

This is my code:

Code: Select all

[ENABLE]

aobscanmodule(MonHpC,MonsterHunterRise.exe,41 89 4B 18 83 E1 03 41) // should be unique
alloc(newmem,$1000,MonHpC)

label(code)
label(return seeMonHp)
registersymbol(seeMonHp)

newmem:
{
R15=0000000000000000
}

cmp r15,0000000000000000
jne code

mov [seeMonHp],r11

 sub eax,C350
  mov [r11+18],0
  mov [r11+18],ecx

code:

  mov [r11+18],ecx
  and ecx,03
  jmp return

  seeMonHp:
  dq 0

MonHpC:
  jmp newmem
  nop 2
return:
registersymbol(MonHpC)

[DISABLE]

MonHpC:
  db 41 89 4B 18 83 E1 03

}

When I hit a monster the HP drops for the first two hits, on the third hit the HP returns to the value it was before hitting the monster. I guess that's why I have to modify this piece of code:

Code: Select all

code:

  mov [r11+18],ecx
  and ecx,03
  jmp return

When I try to use this code:

Code: Select all

code:

  mov [r11+18],ecx
  jmp return

the game crashes.

I found these instructions

on how to do various types of operations, but I don't understand much about them XD

I definitely have to edit the part where there is AND
but I do not know how I can do it. Can someone help me?
Thank you
