[Pre-BB] MapleStory Formula Compilation

From the physical attack code i find many formula we don't knows.
it seems very interesting. Whether it is useful or not, I'll list it here....

================================
Line 170~179,321~333:
v148 = acc * 100 / ( dLevel * 10 + 255 )
physical acc rate=P( random (0.7, 1.3) * v148 >= mobEva )
=P( mobEva / v148 <= random (0.7, 1.3 ) )
=( 1.3 - mobEva / v148 ) / ( 1.3 - 0.7 )
=( 1.3 - mobEva / v148 ) / 0.6
=( 1.3 - mobEva * ( dLevel * 10 + 255 )/ acc/100 ) / 0.6
=(130 - mobEva * ( dLevel * 10 + 255 )/ acc ) / 60

finally...
if acc rate = 0
minAcc= mobEva * ( dLevel * 10 + 255 ) / 130
if acc rate = 1
fullAcc= mobEva * ( dLevel * 10 + 255 ) / 70

================================
fixDamage skill has it's unique acc formula...
the same to #691

================================
Line 786~830:
wand/staff is same as the one-hand axe

================================
Line 364~366----->
if ( nSkillID != 3201003 && nSkillID != 3101003 )
{ //some code }
Line 549~564:
some strange formula...deal with action?..
( dex * 3.4 + str ) * watt / 200

================================
Line 333~352,609,652~
darkness has a 80% base Miss chance
Blast and rush and the 2nd damage of brandish has a change of 60% to force the same action as swing.

================================
correct
================================
Claw (punching):
Min = (LUK * 0.1* 0.9 + STR + DEX) * WeaponAttack / 150

from all formula we have got is that..mastery*0.9..
while I have already confirmed in CMS...

also get some other formula. post here~~
==Prostrate Attack Damage:==
Claw/Dagger:
Max = ( luk + str + dex ) * watt / 200
Min = (luk * 0.9 * 0.1 + str + dex ) * watt / 200
Gun:
Max = ( dex + str ) * watt / 200
Min = ( dex * 0.9 * 0.1 + str ) * watt / 200
(watt not include bullet)
Bow:
Max = ( dex * 3.4 + str ) * watt / 150
Min = ( dex * 3.4 * 0.9 * 0.1 + str ) * watt / 150
Others:
Max = ( str + dex ) * watt / 200
Min = ( str * 0.9 * 0.1 + dex ) * watt / 200

==Punch damage:==
Gun:
Max = ( dex + str ) * watt / 200
Min = ( dex * 0.9 * 0.1 + str ) * watt / 200
(watt not include bullet)
Bow:
Max = ( dex * 3.4 + str ) * watt / 150
Min = ( dex * 3.4 * 0.9 * 0.1 + str ) * watt / 150

not test xBow..
================================
Charge/tap damages for Big Bang/Pierce/Screw Punch:
( 10 + 90 * keyDownTime / fullChargeTime )%
as a modifier.so no Charge as 10% and full Charge as 100%.

================================
Demolition ignores defense

================================
Aran skill Modifier : (36+64 / mobCount)%
Assassinate : darksighttime / 3 + 1

================================
Line 435,453~472: something about Hero Combo:
Hero Combo is multiplied before critical.
another word,it is multiplied by base skill%.
eg: Lv.30 brandish + 10 combos=260% * 190% = 4.94
if critical(lv.30 sharpeyes,no critical rings)= 260% * 190% + 140% = 6.34

Correct me plz if my thought is wrong.

For the aran skill modifier, testing with final blow on two targets always hit 136899 damage, if that helps.
