+This optional rule replaces a character's proficiency bonus with a proficiency die, adding more randomness to the game and making proficiency a less reliable indicator of mastery. Instead of adding a proficiency bonus to an ability check, an attack roll, or saving throw, the character's player rolls a die. The Proficiency Die table shows which die or dice to roll, as determined by the character's level.
+Whenever a feature, such as the rogue's Expertise, lets a character double his or her proficiency bonus, the player rolls the character's proficiency die twice instead of once.
+This option is intended for player characters and nonplayer characters who have levels, as opposed to monsters who don't.
+| Level | Proficiency Bonus | Proficiency Die |
| 1st-4th | +2 | 1d4 |
| 5th-8th | +3 | 1d6 |
| 9th-12th | +4 | 1d8 |
| 13th-16th | +5 | 1d10 |
| 17th-20th | +6 | 1d12 |
