damage calculation?
Hi there again.
i have another question concerning zangband tk 240r5... i compared 2 weapons at the weapon master and i can't seem to work out how he calculates the damage values. the weapons are: lance of extra attacks: 2d8 (+8,+5) dam calc: 1326/strike 3 strikes per turn the rapier forasgil: 1d6 (12,+19), slay animal, frost brand dam calc: 1212/strike multipliers: vs animal 1062 / frost brand 1273 4 strikes per turn concerning the lance it seems to fit (more or less): 2d8+5(weapon deadliness)+5(strength bonus) would make 1226/strike but the rapiers calculation confuses me completely! to me it would seem the damage should be 1d6+19 (deadliness)+5(strength) = 2530 instead of 1212 concerning the multipliers, i'm completely clueless how he did his calculations... am i missing something? or are his damage calculations simply wrong? thanks for helping me out again

ZAngband uses a deadliness percentage rather than just adding the todam bonuses directly. Damage calculations are totally different from Vanilla Angband. You can find an example of how to calculate melee weapon damage in the help files.
In this case I'm not sure what's wrong with the Weaponmaster. Obviously 1212 damage is not possible. That may be a bug. I would have expected to see 112/strike, with an average of about 6 damage/strike. Due to how ZAngband handles deadliness, weapons with low damage dice (such as daggers and rapiers) do not benefit as much from enchantments.

I think what happens with Z's deadliness calculations is that you can end up with a fractional damage die. In other words, if your 1d6 rapier has a 3% damage bonus then you end up doing 1d6 damage 97% percent of the time, but you get a full extra die the remaining 3%, bringing the damage to 2d6. So it could be possible to score 12 damage in a single strike, but extremely unlikely (0.03 /36 = 0.000833).

hm, thanks for all your replies...
i guess i should've realized myself that it has percentile damage calculation, as in my character sheet it's even stated that i have a melee deadliness of 204% (wielding the rapier)... kind of obvious at least this clears up how i can do a maximum damage of 12. actually both maximum damage values make sense now. with the lance i have a deadliness of 163% which means maximum damage is 16+ 10.08 = 26.08... seems fine... but the minimum values don't make sense at all, they're both ridiculously high... well, i guess i'll pay the dear weapons master a few more visits from now on... at least i'd like to find out if his minimum values are really wrong or if they're calculated in a copletely different manner... thanks so far!!!
