It's probably changed since this post on Inven for the original KR release:But hopefully that's useful to some degree?2M per hour cost in silver1% per hour at lvl 57So, lvl 60 would be 0.125% per hour so overnight it could cost 24M for 1.5% - for me that's ok as it literally doubles the amount of XP per day but that would also be at the expense of fishing overnight so the actual cost is a bit higher (factoring in lost revenue).
