This mod is based on the old: "shield and swords mod" of hexxit. It's a remake for the newer 1.15.2 version with better textures, based on the new sword design.
The swords are pretty balanced. Some are stronger and some of them are weaker. It depends on the quality.
None of these swords are overpowered or something else. The mod still gets the "Vanilla Vibe".
There will be updates in the future until MCreator releases a 1.16.x stable patch.
Stay tuned for bug fixes!
