Try this one. I tested it on two different quests only, so I'm not sure if the offset is always valid. Expect a freeze since it's my first code
[Boss 1 Para L + R]
DD000000 00000300
D3000000 00000000
683251F4 00000000
B83251F4 00000000
1000682E 0000XXXX
D0000000 00000000
XXXX = para value
The boss monster part is obviously taken from ymyn's code, so credits for finding the base pointer go to him. This also means you could try to change the 1F4 parts just like in his code and maybe you can use the code for monster 2 etc as well.
You could also try to omit the first line (button combo) and maybe the monster will be paralyzed forever. Just some ideas.
E: Yup, just tested it, leave out the first line and the monster will be paralyzed forever
Well, atleast if you set the para value over the MaxTolerance limit, 2000 should be enough for every monster.
