IGN: Persephone The fourth job Marksman skill "Piercing Arrow" is glitched in that the damage does not increase through mobs hit. The way that it's supposed to work is that it hits multiple monsters (4 between levels 1-10, 5 between levels 11-20, and 6 between levels 21-30) and for each successive mob it hits, the damage is compounded by a certain amount or percentage. I'm not exactly certain of how the mechanics and calculations work, but I know for certain that the damage does not increase at all at the moment. Piercing Arrow allows Marksmen to train more efficiently in higher levels, and it being broken almost makes it inferior to Iron Arrow in that IA is hold-spammable while Pierce isn't due to its charge. I've been unable to find a good example, in either text or video, that explains how Pierce works, but I figured I'd post it here anyway and let you guys do some investigation as well. EDIT: In this video, you can see how somewhat how it works. Skip ahead to about 59 seconds in; you'll notice the closest mob to the player is hit for a 24k critical, while the furthest from the player is hit for a 60k critical. Damage range would not attest for this large of a difference. http://www.youtube.com/watch?v=JQ_Z43ytjBA
