Too many katana users. u.u
I guess I'll make my new character. Say hello to my little friend: THE SCYTHE.
I'll whip up a new character, but first let me toss a few skill suggestions out there.

Sweeping Slash: The user swings the scythe in a 270 degree radius in front of them; depending on the angle of the slash, the scythe can either a) have a chance to crit (upper 1/3), b) hook all enemies hit and drag them into one spot (middle 1/3) or c) temporarily incapacitate them for half a second (lower 1/3).
Last Word: The user dashes in to an incredibly close range and attempts to impale/execute/incapacitate the target. It has a 5% chance of success, but when it does the effects are devastating (can only be used on regular monsters; no effect on bosses except as a gap closer).
Shockwave: The user swings the scythe around them in a circle, damaging enemies and forcing enemies nearby backwards. Anything between the scythe's blade and the user are dragged along for the ride (or used as a pivot, depending on the sturdiness of the thing).
Crescent Moon: The user swings the scythe vertically, knocking an enemy up into the air. If learned, the player may also combo 'Lunar Strike' onto the target.
Lunar Strike: The user hooks the enemy vertically and swings them overhead and into the ground. The impact causes a minor shockwave that knocks back nearby monsters and players and has a chance of incapacitating the enemy in question. Following the impact, the user has the option of pinning the target to the ground, dealing minor damage every second. (Must complete quest to obtain; if used in other scenarios, the scythe kind of just bounces back to the users hand and only does regular scythe damage).
Safe Return: Only usable on allied players; the user uses the scythe to literally drag a player to the user. The scythe does no damage if used, and has a cooldown of two minutes; damage is reduced during this cooldown. The person being dragged has the option of denying the rescue by hitting the shaft of the scythe during its casting; it takes three seconds for the scythe to begin returning to the user, but the return itself in instantaneous. Varies directly to the size/length of said scythe.
Soul Harvest: Passive; Every enemy killed near the user has a higher chance of dropping rare crafting materials. Toggleable.
Death's Door (Unique skill): Passive; the lower the HP of the user is, the damage they take and give is increased. Very high risk/high reward. Toggleable.

Yeah, I don't know how to balance things. Look them over please.
