Congrats, I'm going to work on my last G1 keys and getting G3 tomorrow morning. Hopefully can get it done before the fiancee decides we need to do something.
The damage calcs aren't so bad, actually. Take the attack power of the weapon, divide it by the true raw multiplier, multiply by the sharpness mod and account for affinity.
True Raw Mods:
Hammer/Horn: 5.2
Switch Axe: 5.4
Great Sword: 4.8
Charge Axe: 3.6
Long Sword: 3.3
Insect Staff: 3.1
Lance/Gunlance: 2.3
Heavy Bowgun: 1.5
SnS/Dual Swords: 1.4
Light Bowgun: 1.3
Bow 1.2
Sharpness Mods:
Red: 0.50x attack, 0.25x element
Orange: 0.75x attack, 0.50x element
Yellow: 1.00x attack, 0.75x element
Green: 1.05x attack, 1.00x element
Blue: 1.20x attack, 1.06x element
White: 1.32x attack, 1.12x element
Purple: 1.44x attack, 1.20x element
EX: My post up top.
Ruiner's Bane SA: 810 Attack, 420 Blast, 10% affinity, 2 slots, Elemental phial, Purple sharpness
Affinity: (810/5.4)*.90+(810/5.4)*1.25*.1 = 153.175
Sharpness = 153.175*1.45=222.10
Phial (1.20 for Power) = 222.10*1=222.10
Elemental damage is easy:
Elemental attack value/10 * % shown on chart for body part.
So with a 500 Lightning element on a Monster that shows a 5% on the head you'd do:
500/10*.05 = 2.5 damage.
Statuses are a little different, but based on the charts like the one above you can safely assume which elements and statuses to use and not use.
EDIT: Looks like Gaijin changed his sharpness mods since I made that post above. There had been some debate about if the mod was 1.45 or 1.44 and he seems to have gone the 1.44 route.
Also, am I crazy or was Ash Kecha Wacha somehow stronger than the Raths, M Tigrex, and everything else I've fought so far in C 10*? He was almost always enraged, I bounced off everything except his ass with White sharpness, and was only able to break one of his ears. I could attack his face when he wasn't enraged, but it took the entire fight just to break taht one ear.
