The other day, while playing SWL tournament, I found a really neat trick. It seems that it is somehow possible to hit a Giant in the back of the head with a thrown spear from a Spearton.
This takes the 400 damage of a spear, and adds on the backstab (x2) and giant headshot (x2) bonuses. In other words, it kills giants in one hit and does an epic (though weirdly glitchy) animaion. The animation that plays when a Swordwrath is shot in the head and dies is played on a much larger scale, causing the giant to be thrown back with a suddenly oversized spear.
Anyone else seen this?
