I'm doing more damage from the front now on skills like WFF and SS... Something's wrong here...

It just glitches sometimes and while it shows him with his front to you, he's actually with his back to you.

When u do backslash
At the moment u land attack

For me attack from Behind never work x.x
I have the same dmg from front/behind (by wolf or any needle)

needle dont have bonus if you attack from behind.
only wolf and sword skills.

When i take mouse on Needles its says +50% from behind :o

I have higher damage/crit rate from behind with needle.

I have this problem all of the time with my Swordman and Fighter, Tagi. =/ My Fighter is **** out of luck with this, but at least Swordguys can use an RP ability to keep a monster stunned for two extra seconds and then use Flash to get exactly behind the enemy and then use Unlimited Slash or what have you to deal great damage. I've seen up to 1,500 per slash with Multiple Sword Slashes without any funding/upgraded gear. It's so cool!

at level1 MSS, you could hit, 5.4k xD

Oh, yeah. That's the skill. Multiple Sword Slashes. I don't know why I got its name confused with the HTB skill. lol

In any case, with Kaiouken, the highest I've seen with Multiple Sword Slashes (at level 1) was 9.3k damage.
