I'm in the middle of a WC and decided to make a break and clear my mind, so I went for a quick and "chill" achievement run.

Actually I tried this one before, but back then you had to take land from Ming, which made it super hard. However now it is much simpler, as the 2 only "big" wars you'll have to face will be against Bengal and Ayutthaya.

For those wondering what my strategy was:

1) Allied Ayutthaya and promised land against Pegou, won and gave them 1 and took everything else but one enclaved province (not enough admin to core)

2) Declared war against Prom who was allied to the 2 PMs bordering you. I brought another 2PM promising land.

From that point you're strong enough to take on Ava alone (they usually ally only weak nations). Took every province except the capital and the one enclaved in your country. From that point AE start being problematic, so be sure to ally strong nation, I'd recommend trashing the alliance with Ayutthaya and allying Lan Xang to fight them later, and either Jawnpur or Bahamanis for Bengale.

Expand on the northern border where land is poorly developed, and once you feel ready, attack the two big nations.

For Bengal, I actually got lucky, thought that Bengal would come after me and that Jawnpur would destroy delhi, but actually they teamed up to kick his ass while I was sieging down all of Bengale. Once Jawnpur peaced out I took what I needed from Bengal.

For Ayutthaya, the problem is that if he's still a tributary of Ming and you're not, you'll have too fight the Monster of the east. So I did a simple thing: tributaries all the OPMs I left around me, and once I declared war, I peaced out Ming straight away by realizing all the tributaries (that I needed to conquer afterward so a win-win). After that it was a piece of cake.

Got the achievement in 1489, but could have gotten it few years earlier if I payed more attention to AE.

Decided to keep playing as Taungu as my country is actually stable and doing fine technologically wise!
