DnD 5e hardcore mode solo - Lookin' for Old Betsy

I'm a dungeon slime looking to learn all about what makes humans fear the dungeons so I can become a real dungeon master some day!
I will often be bringing home rules to most games.
I normally use Foundry VTT or a Camera and physical mini's to play TTRPGs solo.
