Nope, just tested it. Berserker's Scythe APPEARS to do more damage because you see higher numbers pop up when you hit him. I was seeing 7 damage a hit with Berserkers Scythe because it's a Demon Slayer, but it wasn't putting much of a dent in his health bar. As soon as i switched to Mystic Hatchet, i was seeing 3 damage pop up, but was seeing his health bar go down about every other swing. The true damage of a Power/Vanq/Mystic Wep is not displayed in numbers above the Berserker, only time it does is if you get the killshot in on him. With the killshot in on my Mystic Hatchet and EoO up on him, i see about 75 damage. They have around 3600 Health. So i was doing 7 damage a hit with Berserker's Scythe, and doing 70s damage a hit with the Mystic Hatchet, at least 10x as much damage. The Hatchet was alot faster too.
