This was definately an interesting boss mob - if you're going to do this sucker, max out your cold saving throw and get yourself a fast casting buff item or spell for your first spell slot - this guy will knock off your first buff every other cast so you want to have a junk buff there to lose so you don't lose important stuff.
As a non-MA in my guild, this is a GREAT weapon - I'm getting off double taps that are just shy of 500 damage with it and the wonderful INT bonus not only helps my casting, but as a tradeskill junky, replaces my MOSS and SoM for INT gear. :)
I initially had a Wideblade before I got the merit for this one. Now, I know a bunch of you are going to say that I'm giving up speed and losing overall damage in the process, but look at these numbers -
Wideblade - max damage = 150, 35 speed
Rekeklo - max damage = 250, 46 speed
So while the Wideblade will swing 1/3 more often, the Rekeklo will do 2/3 more damage.
or
Wideblade swings 3 times for 450 damage in 105
Rekeklo swings 2 times for 500 damage in 92
So as you can see, ultimately, this sword will do more damage in a shorter period of time.
This is a wonderful weapon in anyone's hands.
