wilytilt Posted August 11, 2009 Posted August 11, 2009 I really like figuring out the nitty-gritty mechanics of RPG's I play, and F03 has been harder to figure out than its predecessors which were much more open about their calculations. Since I never found a unified formula for how much damage a player does from doing some searches on forums or the Wiki, I'm trying to figure it out myself from various sources. Here is what I have so far for one shot non-splash guns, with optional modifiers in [brackets]: (BASE DMG + (CRIT DMG X 1.5 [With Better Criticals perk]) - ENEMY DAMAGE RESISTANCE [?] ) x (GUN SKILL)/100x 2 [if sneak critical]x 2 [if head shot; different multipliers for other body parts]x (DIFFICULTY MULTIPLIER) = Damage dealt to enemy Notes:-CRIT DMG only occurs in a critical hit, determined by Critical Hit Chance, which I do NOT calculate here.- Sneak attacks are always critical hits and will double total damage.- Better Criticals increases the critical damage by 50%, and not the base at all- Torso hit multplier is always 1; and I *think* leg hits may be 0.5 or around there. - Difficulty multipliers: V Easy = 2, Easy = 1.5, Normal = 1, Hard = 0.66, V Hard = 0.5 Missing info (please add if you know for sure): 1) I know that head shots on humanoids and some other enemies deal 2X damage, but I'm not sure of modifiers for other body parts. I believe some are less than 1X, like legs, also. 2) I don't know how Item Condition % affects damage. I'm pretty sure it only affects critical hit chance and not damage, but I'm not positive. 3) I don't know where ENEMY DAMAGE RESISTANCE (from their armor) is subtracted from the damage you do. I would assume it's right at the start when you calculate damage before the multipliers, but it could conceivably be at the end (which would make it a lot less useful). Thanks everyone - btw I'm Cholera on the Bethesda forums fyi...
wilytilt Posted August 11, 2009 Author Posted August 11, 2009 Including a quick example ... For a sniper rifle head shot, done while [HIDDEN], with 80 Small Guns skill and Better Criticals Perk, and on Very Hard difficulty... (40 + (40 X 1.5) ) x 80/100x 2 x 2 x 0.5= 160 damage This assumes no effects of enemy DR or weapon condition. This 160 dmg shot would be enough to easily kill a Super Mutant (100 hp) or Mirelurk with a "faceshot" (120 hp), but probably not enough to kill a Super Mutant Brute (250 hp) or Yao Guai (220 hp). I say "probably" because these hit point numbers are from the Wiki and they may be higher than the actual HP based on enemy level.
