I missed this because I mistook it for ShadowSnake's Krystal Mod where a Krystal mesh, some effects, voice clips, and a bunch of other small changes were used over the top of Dark Pit's fighter. Thus, Krystal inherited most of his moveset. That mod worked pretty well, but it was not a completely new fighter.

This new mod, which was a collaboration between Light5585 and much of ShadowSnake's work, has resulted in a complete fighter. This mod gives Krystal her own moves, weapons, and effects.

Here's a video of some Smash players trying it out (Language Warning).

Her Final Smash unleashes a huge blast of both fire and ice from her staff. Her Up-B is the staff's Rocket Boost. Down-B creates a force field that reflects projectiles. Forward-B is Ice Blast from the staff, while Neutral-B shoots a fire projectile across the stage. She runs very fast and has lots of staff-based jabs. She even has new taunts. This really does feel like a complete fighter mod for the game.

As with the previous mod on which this is based, it supports both her Assault and Adventures outfits. The mod has been given a few updates since launch about 6 months ago, with the mod's initial development taking about a year.

The mod can be downloaded from GameBanana, and is about 91MB in size. There are some requirements to get it working on your system, like the previous mod.

Thanks to Light for this amazing moveset, and ShadowSnake for the work on the original mod. This all turned out great! And thanks to Raiando on Discord for bringing the difference between the two mods to my attention!
