I can’t wrap my head around why you can loot random bloody key drops at level 57 combat, but cannot open the bloody chest until you’re level 90 combat. It would be way riskier for lower-level combat players to escape after looting the bloody chest, too.
The combat levels for pures are often between 76 and 90, so it’d be nice if pures below level 90 combat had the chance to open the bloody chest.
