Jebus cross template.

On day 1, you need to have 8 heroes, and then the main hero should gain experience by looting chests. And Besha showed very clearly in a tournament in Kyiv: he says, show me your heroes, how much experience does each one have? - ah, the main hero, that's understandable, the second one has 1046 experience - has he visited the obelisk? - and the rest have zero?... So, each of the 8 heroes should have a lot of experience (an indicator that all the heroes fought, and not just the main hero). Then you will always be able to go to the center on day 121.
