Jolt/+1 are... interesting. Counter is kind of awesome, at least IMO.
For soloing. That is. Every hit you don't take is one less chance for Yoran to "forget" to heal you, and that's a *** win in my book.
Its got enough damage to make your white damage 500+ on attacks (hey money!) it's got enough delay to not hurt your tp gain from martial arts. The counters do 1k+ (depending on target, that's neat).
Is it worth whatever they currently cost for +1, nope. But if you have one/don't care about money they're not as good as REMA but I'd take them over anything else. (commeupennces have very low delay so I don't /really/ know if they're "better" DPS, they're certainly less survivable without the counter+)
I would recommend making Spharai instead of getting +1 made/bought though. If counters are specifically your goal.
