While this skill has some use in niche end-game places (Earth Tower, some Demon Lord Field Bosses), Rank 8 is right around the corner and supplants many previous skills. Regardless, you're going to be lv.130 or so when you advance to Fletcher, and you've got very few precious skill points to distribute. You have three useful arrow skills as a fresh Fletcher and you have...this. It deals anywhere between 0 to 3 hits depending on enemy type. Cloth enemies become scarce late-game, usually restricted to just casting types. Leather enemies are still somewhat common but usually are weak enemies relative to map. Nonetheless, this skill wastes points that could have been saved for the much superior Magic Arrow. You can get a couple points into this if you prefer, since the fake multi-hit is actually a percent mod. However, if you're already leveled and looking for a reset, I'd suggest 5 points in this vs Crossfire. Crossfire is just there for leveling - if you're already circle 2 or greater, consider getting this in lieu of the obsoleted Crossfire, so you can use Barbed for those occasional situations. Furthermore, Crossfire has limited use once you get Magic Arrow. As strange as this sounds, I think 5 Barbed is sufficient if you're looking for a reset.
