Okay, it's just rough, but bear with me.
and a side note. give the entire series it's first step lunge back. it's what made the weapon unique, as it stands, it's garbage.
also another note, these would have different models, and I may or may not upload pictures of how I feel they would look, depending on reception.
both of these follow the winmillion
name: Katabatic Flow (the name for hurricane force winds caused by temperature differences in the arctic)
damage type: piercing
charge attack: a one step overhead cleave (think the triglav/sudruska charge) that tosses enemies back, followed by a vertical wave that either hits an enemy, or once it reaches a set distance, splits like an alchemer line gunshot. just once though. the wave should be fast enough that enemies that can dodge can only do so if they're a significant distance away (3-4 squares) but slow enough that enemies knocked back by the initial swing can be hit by it.
(this has a chance to freeze enemies)
also, like the winmillion disk, this should be able to go through a set number of enemies. (can you stop the wind? xD)
I hate to keep adding things, but also, this shouldn't have the delay that the triglav and sudruska have, like you release the charge, they swing up, and in slow motion, drop the sword (so it looks like it's heavy) these swords are powered, they shouldn't be heavy, they should be quick :D
name: Pyroclastic Flow
damage type: darkness
charge attack is essentially the same as the one above, only difference being that this one has a chance to ignite enemies, rather than freeze them.
no i'm not suggesting an elemental type. there's too many of those.
