He uses that stat in Complete Mayhem.
He always has that stat. I mean his boss fight in 2_B.lua. His stats there are overridden (PedOverrideStat, PedSetMaxHealth, etc.)
I didnt knowed that he uses it in both missions, I was just knowing he was using it in complete mayhem.
PedOverrideStat(idDarby, 38, 50)
It uses this code and is max health is setted to 300
Something that i found a little funny In the mission script is that it overrides is stat 2 times
PedOverrideStat(idDarby, 38, 50)
PedOverrideStat(idDarby, 39, 50)
PS: I read all things again and i understand fine.
