Hopefully More help for Beginners to D&D - I found it a minefield when I first started, so hopefully this will help other novices (and my new players)
EDIT: These are the house rules that we follow when I’m the DM for my group as I use critical fails and success for fun flavour:
In 5th edition Dungeons and Dragons, rolling a natural 1 or 20 doesn’t necessarily mean a critical failure or success outside of attack rolls. (It’s not the standard.) A crit fail on an attack roll isn’t 5e standard either– penalties don’t inherently occur on a 1.
