Type | Size | Attack | Attack Type | Contact Area | Penetration | Velocity | Skill Used | Metal | Wood | Bone | Obsidian |
Mace | 800 | Bash | Blunt | 20 | (200) | 2.0x | Mace | Yes | No | No | No |
War Hammer | 400 | Bash | Blunt | 10 | (200) | 2.0x | Hammer | Yes | No | No | No |
I submit this data from the wiki purely for !!science!!. I can make no conclusions myself other than that the difference must lie in size and contact area, and the fact that they have the same velocity and penetration.
I leave it to an expert to give the real reason.
From my somewhat limited experience, the issue is that you have the same velocity but twice the contact area on the mace.
The mace has double the size(weight?), and double the contact area, but hits with the same force as the war hammer.
So, basically, you have twice the weight spread acros twice the impact area(equal), but the same velocity is spread across twice the impact area(half as effective) as well.
I dunno, i could be totally wrong, but that's my best guess.
Minor Edit: Penetration "size"(from the raws) is likely a representation of how deep into the target's body the weapon can cause damage. For comparison, a spear's stab has the same contact area as a mace but a penetration of 10000. Penetration is going to be relatively useless outside of fighting against extremely large creatures, as most sentients are around the same size and i can speak from personal experience that a scourge(penetration:50) can break a goblin's spine from the front.
