Make some sort of island like it will have place to buy housses , like small house , medium house , and large house taht have function as storange system small will have like example 1k crown bank , medium 3k crown bank , and 5 k for large house , that might be helpfull when you dont want to loose any crown from dead while out adventure , how we can get house ? We buy that from house dealer and when we join the game we must found a place where there is unclaimend house (example : there is unclaimed small house , and you have small house acess then you can claim that house [ONLY 1] in there tou can store extra crown without afraid of losing )
Also , other idea is like a place or village where high levels and other magician live where that will become place where adventurer can claim and under protection of magic council guards in the village. Anyway i cant make it suggestion idk why.
