To make MUNEH you need a PLAN!
Now I am no Van Der Linde mind level.
But I can make muneh like a Lannister shi*s gold.
Early in the game join as many tournaments as possible as you'll get in between 1K-1.2K denars in profit plus the item.\
Be ware as you fight in arenas or gain renown betting on yourself won't be as profitable as it started.
P.S if you are in a Battanian arena and see a lord or worse CALADOG as your potential rival,you might wanna lower the difficulty of AI combat,as they're pretty much untouchable unless you kite their hits perfectly.
Trading is another safe thing to do.
You can buy cheap food,furs,hardwood,leather and sometimes horses from Tyal and Baltakhand and pretty much sell them anywhere.
If you can't trade properly keep in mind every item as this:I bought furs with 30 I sell them no less than 50.
I can guarantee a safe place to trade,though for starters.
Ortysia-Lageta-Battanian Towns-Vlandian Towns.
You can buy salt,silver & jewelry from Ortysia and sheep & wool from Lageta and sell them to Battanian lands since these 2 are at war early on,you can buy hardwood,clay and grapes and sell them to Vlandia,you can buy Hogs and Olives from Vlandia and sell them to NE and WE or just repeat the cycle.
After you earn 15K you invest in these townsTyal, Baltakhand,Ortongard,Akkalat,Odokh,Onira,Danustica,Lycaron or Poros.
You buy Woolweavery or replace a Velvet weavery for it.
The woolweavery will earn you 250 denars/day once it starts rolling in,should be in a few days.
After this you focus on getting high tier units and join NE,SE or WE as you rebuild the glorious Byzantine Empire and make Khuzaits extinct otherwise they snowball too hard.
Don't play Aserai as their units are trash,unless you go for the Mamelukes cavalry and palace guards,but these 2 alone can't win.
Their life cycle also sucks ass,they get their first archers at T4.
And their highest Foot armor is a T3 dropped from looters.
You can even check their units,they use Khuzait armor all around since devs haven't worked on them as they worked on Empire,Battanian,Sturgian and Khuzait.
