well BB is probably the haxest area physical damage available, so i wouldn't be surprised (hax damage, multiple hits on mobs, knockback, cheap SP cost)....
but come on, the strongest 1-h spear at +7 with an element too!
(and don't forget the +800 HP thingie - although -50 SP must be pretty debilitating for a knight, but most spear knights need more vit/HP anyway)
