Reaction Rolls with ... Four Dice?

I believe I’ve mentioned before that I’m thinking about the viability of “4d6, dropping all 6s” as a possible alternative dice mechanic. It give you a 0 to 20 range, within the parameters of some D&D rolls, but with a bell curve… but also, you can use the 6s in a different way to alter results.

Here’s an idea for a 4d6 drop 6 reaction roll table.

4d6 drop 6 Reaction Detailed Explanation
Up to 1 The Worst Enraged, immediate attack.
2-3 Very Bad Hostile , will attack. No further offers.
4-7 Bad Unfriendly and threatening. Refuse offer.
8-12 Normal Neutral but uncooperative. Ask much more on offer.
13-16 Good Open and cooperative. Ask a little more on offer.
17-18 Very Good Friendly and helpful. Accept offer.
19-20 The Best Enthusiastic, offers help or discount.

As with a standard reaction roll, this is used for two main situations:
  1. Potential combat situations (Will the opponent be hostile or even attack, or will they be open to parlay?)
  2. Negotiations (Will the NPC accept the offer, ask for more, or reject the offer and refuse further haggling, or even hurl a string of insults or accuse the PCs of being a thief?)
If the result is 4 or more, but one or more 6s were rolled, a special effect may be triggered, if one is present. Some special effects:
  • Lying: The NPC or monster pretends to have a different reaction, usually to trick the PCs.
  • Personality Trait: NPCs or monsters may have unusual behaviors or goals that trigger if one or more 6s are rolled, for example “looking for the perfect sacrifice to their dark god”. Alternatively, PCs who have personality flaws, such as “accident prone” may exhibit these flaws, perhaps explaining a bad reaction, or simply causing embarrassment during an otherwise successful negotiation.
  • Curse: If a PC has a curse effect waiting to be triggered, it takes effect at this point. For example, “haunted by a shrieking ghost” might result in the ghost appearing while trying to find a room at the inn.

  1. Very interesting. I've checked the probabilities of this:

    Probability distribution:

    Value *** % = ******** % ≥
    0 ******* 0.077 ****** 100.000
    1 ******* 0.309 ****** 99.923
    2 ******* 0.772 ****** 99.614
    3 ******* 1.543 ****** 98.843
    4 ******* 2.701 ****** 97.299
    5 ******* 4.321 ****** 94.599
    6 ******* 6.173 ****** 90.278
    7 ******* 8.025 ****** 84.105
    8 ******* 9.645 ****** 76.080
    9 ******* 10.802 ****** 66.435
    10 ****** 11.265 ****** 55.633
    11 ****** 10.802 ****** 44.367
    12 ****** 9.645 ****** 33.565
    13 ****** 8.025 ****** 23.920
    14 ****** 6.173 ****** 15.895
    15 ****** 4.321 ****** 9.722
    16 ****** 2.701 ****** 5.401
    17 ****** 1.543 ****** 2.701
    18 ****** 0.772 ****** 1.157
    19 ****** 0.309 ****** 0.386
    20 ****** 0.077 ****** 0.077

    Average value = 10.0
    Spread = 3.42
    Mean deviation = 2.74
