AH. Knockdown lolstabs would be a hoot. I don't know why more people don't use the goat-tag. Fast, long, can lolstob, knockdown, etc.
had to check the shop it does pierce on stabs !
no lolstab knockdowns lol
and if I had to make a guess as to why it's not used that often it'd be because of it's low-low base dmg, even lower than the warclub means that a high cut weapon will out do it (if you're not a wimp and have like 6-7ps) the majority of the time in damage as well as having the bonuses the cut weapon may have (faster speed, shield breaking, more damage on stab, length, less weight)
