I thought about creating a basic Katana for Typhlosion using a simple color palette, but I noticed this really nice Katana in the mods that actually had really nice layering in it's Materials, allowing a quick glow effect to be applied. While I could have adjusted all of it to be more like the sprite (like a lightsaber.. katana thing), I actually really like the pattern on the blade and think it fits quite nice.
Sure, low effort, but it looks better.
The trickiest part here, as usual, was the flames, but I think the final result looks great. Sub turns it off, including the blade, and the floating orbs are not included, because of nodes. I don't think there's much else to say.
Enjoy!
