I own this scythe. It's the one I use in EXP and God pt's.
Same damage and delay as a Death Scythe, plus the added 2 ACC and magic ACC. Very spiffy, very nice. When fighting things like Byakko, every bit of ACC counts.
I still use my Death Scythe for soloing and farming. All in all, this is one of the best scythes in the game.
It is real, I've seen a couple of people on Fairy with one, and one Triton's scythe too. Of course I think they could've given it more accuracy. +2 isn't much considering there are some weapons that give you +5 accuracy at a much lower lvl. But damage is nice, even though there probably is better, but still it is a decent weapon.
Orichalcum Scythe is real, it looks like a Darksteel scythe just has a silverish collar just below as teh brim. i couldnt get a snapshoot of it because the jp player was running, and kept switching his armor so no one could peek at his gear which i find retarded. Who ares if someone glances at your armor it gives you one more reason why your 1337. anyway i Have seen him running from the northern mog entrence to south, i hope this helps in uncovering its realness.
If it does, ive never seen it, or the tritons scythe for that matter. Some says tritons is 3 mil on their server, its never existed on Ifrit that i know of :P
