📋 About This Mod

Open Source Armory

Greetings Warriors!

HalfMetalJacket, Apolon21, Diakonus, Genrev Pogi, Terco_Viejo, AlphaOmegaMan, Maverick_Knight, Philozoraptor, Basileus, Balbor, Dzor7266, Lemanier, Alexander Drakos, Plebeian Kilo and I are pleased to present the Open Source Armory project! This mod combines many of our published armor/weapon/item mods into a single file for easy compatibility with your favorite troop mods, with bug fixes, optimizations and some exclusive never-seen-before items!

All the items are 100% lore friendly and are tailored around the established aesthetics of the vanilla game. Wherever possible, real historical examples of armors/weapons have been used as inspiration, with low fantasy concepts filling the gaps - just like the vanilla items our mod is based on.

All items are balanced and set to appear in the stores in towns across Calradia - for a price! However, items will not appear on NPCs - you will need a dedicated troop overhaul mod for that! If you are loading the OSA on your existing Bannerlord campaign, be prepared to wait several in-game weeks for items to appear in shops, as it takes a while for the shop inventories to reset.

If you have any requests for custom armors you would like to see added in the future, make sure to comment in the Posts section, and we will see what we can do! Please keep discussions constructive. We are a completely volunteer team who mod as a hobby. The OSA is a 100% not for profit passion project - just the way it should be!

The OSA now has official Discord channels over at the Calradian Reforms Discord server. Join now at: https://discord.gg/bwvUUQTnHE

NOTE:

The OSA now relies on assets included by Taleworlds in version v1. 4. 0. As such, version 2. 0. 0 of the OSA onwards will require a version 1. 4.x installation of Bannerlord.

NOTE #2: Due to changes made in version 2. 0. 0, updating from a previous version requires you to delete all OSA files from the /modules directory before installing the new files.
