The additional effect on this weapon goes off quite a lot - several times per mob in a party is common to see. It makes this an incredibly cheap and quite viable weapon to use as every DD benefits from the evasion down.
this is a good GK to have. very affordable and evasion down as said before is great to have. its awesome to use when fighting eva. mob like Lesser Cabrili. eva down gives everyone a nice shot at it. good buy...
At this point you pretty much have to weapons worth having until 59 when you can equip Daihannya; Dotanuki or Soboro Sukehiro. Of course Dotanuki is great for all DD's in a party but Soboro Sukehiro has higher DPS and could stack more TP. It's all based on what monsters you're fighting which is best to use.
The evasion down is nice to have but the damage on this is sub par for the level. Once you hit level 59 you're going to want a Daihannya. Dotanuki is a suitable weapon until then.
