Per a request from Slifer135, I built the Holy Avenger as it appears in the PHB, with no extra fancy nonsense whatsoever.

Then, I thought, why stop there, and so I made more weapon types that the Holy Avenger does not appear as in the PHB. If you only want the greatsword, longsword, shortsword, rapier, and scimitar version, then the base mod is all you need. However, if you're feeling like your paladin needs a battleaxe, greataxe, dagger, spear, halberd, warhammer, maul, or mace, then snag the add on file. You have to have the base for the add on to function and spawn properly, but otherwise they shouldn't have any dependencies. As always, all weapons will spawn in their own chest in the tutorial chest, Damon's inventory, and Sorcerous Sundries. All of the weapons have the same stats and buffs, which function as it says on the tin. Only thing that I couldn't do exactly as in the PHB was make the aura increase in size at level 17 of paladin. Someone with more know how might be able to make it increase, but I couldn't figure it out.

The add on also comes with 3 of the mightiest weapons known to mankind: THE HOLY HAND GRENADE OF ANTIOCH. 

UPDATE, 6/11/2024: The extra weapons have some issues with how they're held when wielded with another weapon or shield. Namely, the warhammer, spear, and battleaxe get real buggy the moment you try to hold them with anything else in your other hand. I've tried to figure out why and how to fix it, but so far I've had little success. To that end, I implemented a temporary workaround by making all three of these weapons two handed. I checked with the strong and base body types, and they all are held properly now, but this does limit how they can be used, unfortunately. If I can figure out how to fix the issue, I'll remove the two handed trait, but for now, this is the only way I've been able to figure out to fix it.

Have fun.
