D&D5e Survival. How long can you survive?

Ah, yes. So here you are...  adventurers lured into a cave by treasure only to figure out the dungeon is filled with deadly creatures. You must now fight for as long as you can until death. This is a D&D 5e game that will have you at level 20 Characters. You will be given a set amount of gp and will have to survive as long as you can with your fellow party members until your death. It will start out easy with something like a rat to an unimaginable horror. How long can you survive? Write a reply if you are interested in joining. [Edit] We have two players and are currently looking for more.

Hi there-  Sounds fun, but day/time is my issue (stupid work).  When do you play? I'm in CST, and I have an alternating two-week rotating schedule that causes me lots of problems. Thanks! Meg

I'm still kind of deciding the time, but It will most likely be on Saturday  afternoon Eastern Standard Time.

If you don't mind working around my stupid work schedule, this sounds fun.  I'm off 3/11, 3/25, etc (in theory).   I'm also open to whatever race/class to help round out the party, but usually enjoy playing a tank character.   Thanks for your consideration!

I can probably work around it. Your welcome.

This sounds like a lot of fun, a one shot I  presume. By saturday afternoon, do you mean Mar 11?
