Just a little bit of a tip. You should always check the sarcophagus first. When searching the chest, you may get the swarm bugs as a trap. If they appear, they will be aggressive to the point where you can't check the sarcophagus. If you check the sarcophagus first, you will still be able to check the chest even if you get a swarm/zombie. Edit: BTW, i got the Scepter on floor 5 in the sarcophagus after about 12k exp and ~20 minutes
