Suggestion: Store currency

Let's be real. The whole store needs to be adjusted. It's extremely expensive for no reason and the items themselves are not worth the price. They're outdated and should be updated once in a while. Take Nether Shop as an example. 10 Frost Scepter shards cost 8k 'proof of battle' (that's the name of its currency). What even is that? Do they know how long it takes to reach that currency?

We need a QoL update!!!!! We require one!
