@Kiro Well, you technically could. It has to do with magnetization areas and the fact that lightsabers are believed to be made of plasma. If anything, the lightwhip is less possible due to the gravity effects that makes it a whip.
Anything is possible if you have the willingness to work on it. Curved lightsabers were discussed in a previous thread and the consensus was they were possible, but serving no additional benefits. But that just means there's no additional drawbacks either. So if you'd like to make a curved lightsaber go for it, just know it's not going to have superior cutting power to a straight saber. As for the scythe, I'd suggest making a tech writeup for it maybe? I'm not sure if you need to for individual pieces of tech. Getting a good visual in your head works well, like for example the Deathscythe's gundam from gundam wing.
And remember that you'll need to work harder explaining your attacks or actions with this saber. As well as acknowledging the flaws of the scythes design, such as its long hilt that can be struck for damage, or it's restricted angles of attack.
That's pretty much what I said.It'd be a goofy weapon but it's not impossible. It's just a special snowflake.
The thing to keep in mind when picking weapons like this are the angles of attack. Your limited to side-thrusts and a standard thrusting attack, but just angling your handle off-center to hit them with the saber blade. You won't be able to block well with this weapon either, so I would focus on a style of speed and offensive capabilities rather then wasting time on defense. No soresu scythe twirling here. Most likely, if you're serious to do this, I'd suggest ataru or niman for your style. That way you can sure up your shortcomings with martial arts or force techniques.
YesHey, I know I may sound like a darn 7 year old for this, but I wanted to have my character have a crossguard lightsaber. Is that currently allowable?
That lightsaber reminds me Waaaaaaaaaaaaaaaaaaaaaaaaaay to much of Meryll from the walking dead.Currently the Wrist Mounted Lightsaber is a usable weapon.
