About mana regen - Xidd - 11-26-2010
the mana regen formula in lf2 is: (500-health)*0.01 + 1
if it is a special char then (500-health/2)*0.01 + 1
mana is added every 3 TU's
clones(rudolf and maybe something else?) cannot have more than 150mp
you do not regen mp while you are *flashing*(invincible)
for characters with more than 500hp - 500 is used as the health instead of the real value
you can find the code at: 0041FA7Bh
the code was rewriten so that instead of using 500-health it will use max_health - health
the code was also cleaned up and lots of useless stuff was removed

ASM-Code:

it is a cleaned up version of the original code except it replaces edx,500 with mov edx, dword ptr ds:[ecx+304h]
if you want to add it to the dll then:
invoke JmpPatch, 0041FA7Bh, addr mp_regen
this should make boss fights much more challenging
