Attack Momentum

Before this change the first two formulas for an average dwarf with a steel battle axe gave the same result of ~93.75, after the change the result for the 2nd formula is 367,968,750. I've checked my math with WolframAlpha here (1st formula), here (old 2nd), and here (new 2nd). The 3rd formula (added in the same edit as the 2nd) has never quite matched either of the others giving a result of ~92.86, but it's close.

I don't see the point in having the variations, but I also don't hav the technical abilities to verify if any of them are currently correct. Ziusudra (talk) 07:05, 19 August 2024 (UTC)

Attack Momentum Costs (blunt attacks deflection/bouncing)

The bouncing/deflecting condition of blunt attacks: (2 * Sw * IYw < A * Da) where Sw is the weapon size, IYw is the weapon (material, I think) impact yield, A the contact area and Da the armor material density, doesn't take into account the weapon material density. I think this is wrong since in game the material density of the weapon affects. For example, in game, Adamantine hammers bounce and steel hammers don't while in this formula Adamantine hammers should have an easier time not bouncing due to their superior characteristics (steel has 1.5 million IY while Adamantine has 5 million). I think there is either a missing element in the formula (something related to the momentum perhaps) or there is something I'm not understanding. Jose96xd (talk) 08:55, 24 October 2024 (UTC)

Material and item properties

There is a claim that states that "a platinum war hammer ... gets about 12% more momentum over a steel one... An adamantine hammer, however, only has 1/7th as much." There is no source for this affirmation, and I think it is wrong. In the same article, in the "Attack Momentum" section, there is a lot of calculated momentum, and the difference between a steel axe and an adamantine one is 2/3, not 1/7 (68 adamantine vs 92 steel).

Now, the affirmation was for hammers (which, for momentum, are basically half an axe) so I redid the math again, but with hammers. Results: 147 steel vs 85 adamantine. Roughly half, but way more than 1/7 of 174 (21). I think there is something wrong either with the table or with some of the formulas.

(Note: The used formula yields the same values as in the table when using axes, so I think it works fine). Jose96xd (talk) 10:04, 24 October 2024 (UTC)
