Currently using a very large modpack on 1.5.9. Tons of content, tons of fixes to get it to work. Sadly author did not get permission from modders to make/modify these and distribute them so.. no longer public. But this encouraged me to explore mods tenfold and make my own (once I do, get permissions and share with others).
That being said, I am still on 1.5.9 and will progress to 1.6.0 in a few weeks maybe, but here is a small list of mods I recommend and what versions they are supported for. I haven't used 1.6.1 yet but I'm sure some of these will work.
- Adonnay's Troop Changer (heavily customized settings, allowing new units to be recruited - 1.6.0+)
- Attributes Matter (modify bonuses for attributes - 1.6.0)
- Bandit Armors (small armory mod - 1.5.9 / 1.6.0 beta)
- CA Eagle Rising (large faction overhaul - 1.5.9 preferred, works but auras broken on 1.6.0)
- Calradia Expanded (map overhaul - 1.5.9 / 1.6.0)
- Calradia Expanded: Kingdoms (faction overhaul - 1.5.9 / 1.6.0)
- Calradia Rising Armoury (medium sized armory mod for some slightly less quality troop mods - 1.6.0 / seems to work on 1.6.1)
- Calradia At War: Custom Spawns (faction/troop overhaul mod, really nice - 1.5.9 only afaik, haven't tested on 1.6.0+, seems abandoned
)
- Custom Troop (make your own troop tree within Kingdom menu - 1.5.9 / 1.6.0 / 1.6.1)
- Dismemberment Plus (self-explanatory, must-have - 1.6.0 but thanks for telling me it works on 1.6.1)
- Distinguished Service (promote troops who kill enough in battle to companions - 1.6.0 / 1.6.1)
- Freelancer (enlist yourself under parties as a soldier, recommended! - 1.5.9 / 1.6.0 / dunno if it works in 1.6.1)
- Improved Garrisons (lots of QoL stuff for garrisons - 1.5.9 / 1.6.0 / 1.6.1)
- KaosesTweaks (just guess - 1.5.9 but works with 1.6.0)
- More Troops mod (lots of custom armor stuff, requires OSA - 1.5.9 but works with 1.6.0)
- Reskin Rearm (lots of custom armor stuff, requires more Troops Mod/OSA, 1.5.9 but getting an 1.6.0 update sooon!)
- Open Source Armory (large armory mod, must have - 1.5.9 / 1.6.0)
- Party Screen Enhancements (self-explanatory, must have - 1.5.9 / 1.6.0 / 1.6.1)
- Realistic Battle AI Module (big smart AI - 1.5.9 / 1.6.0 / 1.6.1)
- Realistic Battle Mod (armor and weapons go brr - 1.5.9 / 1.6.0 / 1.6.1)
- RTS Camera (controlling troops like an RTS, some qol stuff - 1.5.9 / beta 1.6.0 but works on stable 1.6.0)
- Swadian Armory (medium armory mod - 1.5.9 / 1.6.0)
- The Valkyrie (female troop mod - 1.5.9 / 1.6.0)
- Xorberax' Cut Through Everyone (self explanatory, not updated in a long time, but another author updated it for 1.5.9 and 1.6.0 see "broken mod fixes")
Couple of notes: Realistic Battle Mod is not compatible with Calradia at War Custom Spawns, CA Eagle Rising, CE: Kingdoms, Valkyrie, Bandit Armors, etc. They will need RBM patches. Open Source Armory, More Troops, Swadian Armoury, Calradia Rising Forces Armoury .. all have patches.
