One of the things that makes my D&D games a bit more unique, is the use of Critical Hit Dice.
These are custom dice that my friends and I have used in AD&D games for years. Here's how it works:
If you roll a natural 20 on an attack then you get to role the Critical Hit Die. You might get Double Damage, Stun, or even an instant Death!
If you roll a natural 1 on an attack then you must roll the Critical Fumble Die. You might Fall Down, Hit Your Ally, and get Knocked Out!
If you roll Sever Limb on the Critical Hit Die, then you get to roll the Hit Location Die. You might sever an Arm, a Leg, or even a Head!
Now as all of my games take place in Roll20 I created a tables and macros to replicate these dice. So now I am going to share with you how I created these macros so that you can create your own within your game! Here are the screenshots for you:

And then I add these three dice as Buttons on my screen
