So spikards, is that extra damage or a second (unrolled) attack? The text is somewhat misleading. I've been going on the latter.
So I thought, lets pimp one out and see if it needs more bling.
Dwarvencraft Splitting Quickloading Dwarven Mauler War Spikard (+1) loaded w/tumbling bolts, bayonet, spike shooter, crossbow sight, wand chamber, and receiving Greater Mighty Wallop = 8d6+10d6+2+10d6+2 (*4 v giants/goblinoids) (73.139) Not legit but humorous.
