I did some interesting weapon testing in the arena today with v.31.10. Here are the scores of the tests in terms of dwarves left standing. Each match has 20 combatants, 10 on each side, starting in line formation 2 paces apart.
All dwarves have the following skills:
Skilled Fighter
Skilled Shield User
Skilled Armor User
and where applicable, Skilled *weapon* (mining pick uses mining skill which is unsettable in arena)
The armor is:
Steel Mail Shirt
Steel Breastplate
Steel Helm
Steel Gauntlet x2
Steel High Boot x2
Steel Greaves
Steel Shield
First I wanted to test whether silver was really the best choice for blunt weapons:
Silver war hammer vs. Steel war hammer: Winner, Silver war hammer with 8 dwarves standing.
Silver war hammer vs. Steel battle axe: Winner, Silver war hammer with 9 dwarves standing. (* this surprised me a bit *)
Silver war hammer vs. Silver battle axe: Winner, Silver war hammer with 10 dwarves standing.
Silver war hammer vs. Adamantine battle axe: Winner, Adamantine battle axe with 8 dwarves standing.
Then, Ive seen some really crazy stuff happen with mining picks, like my legendary miner wiping out a squad of goblin ambushers, and getting killed by a goblinized human miner in adventure mode after killing their general and other soldiers easily. Also, in arena mode, you can't set the mining skill, but skills increase very rapidly. Unskilled miners are up to expert or higher by the end of these battles.
Unskilled copper pick vs. unskilled steel battle axe: Winner, copper pick with 7 dwarves standing.
Unskilled copper pick vs. Skilled steel battle axe: Winner, copper pick with 4 dwarves standing! (* this surprised me alot... kinda*)
So anyway, it looks like that embark mining pick is one of the best weapons in the game. I knew it!
