Mace
A ball covered in spikes that weighs 10 kilograms. In fact closer to a morning star than a true mace.
Stock
In stock, the mace has 1000 HP, 0.5 piercing and 0.5 concussion.
It was discovered to be more effective than previously thought by Sage and InfiniteInertia, even more so against the weapons previously perceived to be the most powereful, the razor tip and the iron spike. This is because the shape of the mace protects the extenders better than irons and razors AND because their much higher Concussion stat reflects more damage to weapons, hence it beats razors and irons for the same HP.
Mostly used on HS and Rammers, it is notably the main weapon on Infiniteinertia's Absolute Chaos (and various other 36-HS) and Clickbeetle's Frag Beetle 3.
DSL
In DSL, the mace has 2200 HP, 0.9 concussion and 1 piercing (274 DP).
Mostly an unused weapon because it doesn't deals really high damage and has only standard fracture.
