Ask an Aran thread.

What do Arans max after Full Swing and Combo Critical? I saw a build that suggested Smart Knockback next but it doesn't seem that useful early on. Would Snow Charge next be a better option?

Also, does anyone know if maxed Whirlwind works on bosses?

Smart Knockback is ridiculously useful for training at gallopera. And unless you're in scania it's not unlikely that you'll find a map to share with someone. Two arans splitting the map is ridiculously fast exp. I was getting about 40% per hour at level 95. Clean weapon. Oh, and Fenrir is also surprisingly good to use just as monsters spawn. It's best not to use it as a finisher, since most of the time max fenrir was OHKOing fresh spawns.

Oh and even level 5ish fenrir was OHKOing them sometimes.
