This mod contains many Dark Souls 2 enemy, boss, and NPC weapons and armor pieces, some unused in the final game. Some examples include the Suspicious Shadow's Rapier, Dragonrider's Axe, and Ironclad Club and Shield. Some player weapons are also included, as the enemy or character that used them had additional models, such as Gilligan's second Melu Scimitar and the Blacksteel Blade sheath from the Allone Knights.

Each item is set up to replace another specific item, though you may change the ID of an item to one of your choice, provided you know the ID of the item you'd like to replace.

Disclaimer
As these are model swaps, you should not be banned from online play. However, there is still a possibility as you are modifying game files. Use at your own risk.
Additionally, you may have larger or smaller hitboxes depending on the weapon chosen. This can give an unfair (dis)advantage in PvP.
If you are using Mod Engine, then you will be banned if you go online.
