Level 280 daily meso limit: 170 million

Level 280 monsters, 18,000 per hour, net meso: 37.8 million

You can reach 170 million in 4.5 hours of hunting, but considering Polo and dropped meso in between, it will be full in 5 hours.

Meso Acquisition 177% (Equipment 100 + Union 4 + Ability 15 + Wealth Acquisition Potion 20 + Artifact 12)

If you hunt for 4.5 hours, you earn 100 million meso per hour, so it will be about 450 million meso. If you have 20% ability meso acquisition, it won't be 500 million

Here's a link for those who are curious about simulations that fit their conditions. It's in the Wealth Acquisition Hunting Sheet.
