I love a good random table, but my problem with some charts is the distribution. A simple d100 for a chart is a linear distribution, but if you roll multiple dice, like the 3d6 for character generation, you get more of a bell curve with most rolls falling in the middle, around 10 or 11.
So with distribution in mind, I have put together a quick little fumble chart for when you roll a natural 1 on the d20. (There’s a nice printable version on GM Binder)
| Roll | Result |
|---|---|
| 3 | Self KO. Make a DC10 Dex save or knock yourself out. 1d6 rounds unconscious unless roused by somebody, or take damage from any source. Start your next turn Prone. |
| 4 | Pulled up lame. Make a DC10 Dex save or move at half speed for the rest of this encounter (or until healed) |
| 5 | Turned yourself around. Somehow you spun around and turned your back on the opponent who now gains 1 attack of opportunity against you. |
| 6 | I meant to do that. You miss in such a comical way that your opponent must make DC10 WIS save or be incapacitated laughing until the start of your next turn. |
| 7 | Two left feet. Drop to the bottom of the initiative order. |
| 8 | Really poor footwork. Drop 2 initiative level |
| 9 | Poor footwork. Drop 1 initiative level |
| 10 | Epic Fail. Your friends will tease you about this for weeks to come. |
| 11 | Epic Fail. Your friends will tease you about this for weeks to come. |
| 12 | Poor footwork. Drop 1 initiative level |
| 13 | Your next attack is at disadvantage |
| 14 | All attacks against you are at advantage until the start of your next turn. |
| 15 | Weapon slips from your hand and lands in a random square 5ft away. Roll 1d8 to determine direction with 1 being directly in front where the PC is facing, the count clockwise. |
| 16 | Weapon strikes and gets lodged in wall/floor/furnature within 5′ of you and requires a DC15 STR check to pull it free. |
| 17 | Self Harm. You hit yourself. Roll damage as normal. |
| 18 | Self Harm. You hit yourself and do full damage to yourself. |
