Hello guys, I want to know how many slots occupied i can have to join at olympiads, i saw one guy in a vid that have like 8 rows full of items, and i go oly all time with 6 fulled rows.. Someone can tell me max slots occupied can i have to go join oly?

it depends on how many maximum slots you have expanded...if you expanded inventory with fishing proofs you can use more slots at oly....im not sure maybe 80%

I have like now /104 to put items, and have also belt to make it more slots.

If you have 104 slots, then you should have 82 or less items which would be around 80% of the inventory capacity.
