Hello guys, Hedger here. I wasn't quite sure exactly which part of the forum to post this so I figured General Discussion would be best. Anyways, I was experimenting with the Piercing Wedge wand skill after I had got some in the skill card dungeon at various ranks, as I've never seen it used in action before and wanted to see if it would be useful. After building up a Reptos (http://onigiri.wikia.com/wiki/Reptos), which actually isn't too bad of a weapon btw, if you can identify it easily, I collected quite a bit of them identifying the weapons on hell for the daily stones (cost effective way to identify 300 weapons for the monthly artisans) and you if have some spare dura tickets and/or a tailor on you (since base dura is below 1000), it does around the same damage as an Inti Raimi.
Having placed two rank V's and a rank VI version of this skill on the Reptos (saving the Rank VII for the ideal weapon that I have in mind for this setup, which I'll get to in a bit) I tried it out running a couple dungeons and I was quite pleased with the results. Rank V hits about six times and Rank VI about eight. While it might not be the most damaging skill out there (that depends on if you can get all the arrows to hit), it has decent cool down and AMAZING durability consumption, it uses up 1 durability point per tick, so it's very good setup to have if you haven't built up dura on your weapon yet, since it takes REALLY long to use up a substantial amount. It has decent mobbing potential, if you gather them in one area and quickly fire off all three. You can't roll out if it, but you can cancel out of it by using another skill.
Now the weapons I really want to test this on, are the Lancelot wands, which I don't think there's a wiki link for, but give you 15 to 50 Pierce element, depending on which Wand you craft. But seeing as I'm at level 111 and still have a crapton of farming and levelling to do, I can't tell you how the experience is there. This is very niche, but I wanted to put it out there in case anyone might want to try. You'd have to run the skill card warding a lot and this skill doesn't seem to drop as frequently as the others (although that might be just my experience) and the weapons aren't the easiest to get, unless you want to try on something without the Pierce element. But if you get enough of the skill cards and the right weapon, I think it would be a useful addition to a wand user's arsenal.
