i think rumor is a good partyof 55 can take it but it would be one hell of a fight. or....
you can get a 75 rdm/whatever sub to go in and kick its ass.
i've seen rdm/whm do this guy lol talk about making the dude a freaking joke
If a 70 sam, 60rdm, and 75 blm can take him i'm sure you could handle it. he'll i'd even come duo it with you on whm if you'd like if that would make you feel safer ^^
get {Savage Blade} so we can do lvl 3 light that be da shit
