Showcasing a new weapon featured in the new update for the souls weapon transformations mod that adds in 2 form weapons with powerful abilities. You can find the mod here on nexus www.nexusmods....
At first, I got excited for a seemingly more grounded weapon that matched ER. And then was immediately disappointed to see yet another “become a boss but is dog shit for a player to use this moveset” mod
If you want "grounded weapons that match Elden Ring" - try Reforged mod. It has a lot of weapons, and virtually all of them are basically either just normal weapons of their class that isn't in base game, or the normal weapon of its class but the skill has some small additional effect. Like marionette's sword. It's just straight sword. Or there's like a curved greatsword with totally normal moveset but the ash of war is lion's claw that leaves small fire AoE. Very grounded. Very fitting. Enjoy! Very worth installing mods for! Not for me tho, there's already more than enough clutter of weapons that have no reason to exist other than having different model
