As far as ones that I know have been implemented into the game, there are no blue-colored scythes at all, much less one that warrior can use. The closest one that I know of that's in the game is the Enforcer, but that is Dark Knight only. Now there is an unknown scythe in the .dat files that is blue and gold in the fashion of a Zaghnal (which Warriors are often able to equip) but I don't recognize it as being an existing scythe in the game so much as one that was added in the .dats but never implemented.
