Variant Rule: Proficiency Die

From the 5e Dungeon Master's Guide...

Rather than gain a flat bonus called proficiency, you gain a proficiency die which is rolled to determine your proficiency.
+2 = 1d4
+3 = 1d6
+4 = 1d8
+5 = 1d10
+6 = 1d12

If you have Expertise, you roll two dice.

If you would have half proficiency, you roll the die and divide the result by 2, rounding up.

I do not approve.

Proficiency is a nice flat bonus. I’d rather have a reliable bonus, than a random risk-reward one.

Maybe if a player wanted, they could opt for the die roll rather than the flat bonus, for a singular instance where proficiency applies.

I’ll consider it. I am a fan of not having flat bonuses so that there is more risk involved in the things we do, and it allows for those who are proficient in something to sometimes “goof up” (a roll of 1) and sometimes excel (a higher roll). This is a similar change I proposed for the Barbarian’s rage die, or even the defense roll. I just happened upon it in the forums. Perhaps it could be something like HP rolls, where you take the average or the die roll. We will see!
