Crusader Kings II

[Monk]

Yikes. I've been playing a game in Spain and the British Isles (I swapped to an Irish count of my dynasty once I became Emperor of Hispania), and so hadn't really given much thought to the Hordes, especially after they both near-simultaneously converted to Nestorianism. However, whilst idly browsing the 'independent realms' ledger I noticed the Ikkhanate has a 250 thousand strong army, with the Golden Horde having another 150 thousand. I'm thinking once I've fully united Britain I'll switch to the fairly powerful Kingdom of Greece (also of my dynasty) and see if I can take them on. Are their troops still resistant to attrition after they convert?

Wow, what? That can't all be doomstacks... how big are the hordes in your world? Show us a screenshot!

edit: As far as I know, once the horde converts they can still use their doomstacks (and yes they are attrition proof) but they lose the ability to call their powerful invasions. They are forced to use the claim system or fight holy wars for single duchies at a time.

Fortunately, if they are powerful and have large areas of land, those numbers you are seeing might be coming from more traditional levy and retinue caps which do suffer attrition.
