<3 Hugs Kabutowari +1
got one, saving up for the other, rarely sold on my server. this is where it's at from 61->66 ... @ 30k xp per level they'll last quite some time for most ninjas.
.1145 damage/time ratio vs. .1396 (.0251 diff very nice upgrade)
the level 66 +1's are .1396 vs. .1541 O_O (.014 diff a substantial upgrade)
the Kabutowari is the first damage upgrade since level 46 other than the ultra rare/ex(pensive) shinogi/hocho/kageboshi
