D4 Dice Roller
Roll the four-sided die online — the caltrop-shaped d4 behind daggers, magic missiles, and Bless in D&D.
About the D4
The d4 is the smallest standard polyhedral die: a tetrahedron with four triangular faces. Unlike other dice it does not tumble well, so you read the number printed at the top point (or upright along the bottom edge, depending on the set).
Every face has an equal 25% chance and the average roll is 2.5. In D&D it is the die of small weapons and small blessings — minor damage, minor boosts, and the extra kick on healing potions.
What Uses a D4?
- Light weapons: Daggers, darts, and slings all deal 1d4 damage in D&D 5e.
- Magic Missile: Each dart deals 1d4+1 force damage and always hits — three darts at 1st level.
- Bless: Adds 1d4 to every attack roll and saving throw for up to three creatures.
- Guidance: The cleric cantrip adds 1d4 to one ability check.
- Healing potions: A basic Potion of Healing restores 2d4+2 hit points (average 7).

D4 Probability
Each face of a d4 has an equal 25% chance. Common d4 rolls:
| Roll | Average | Range |
|---|---|---|
| 1d4 | 2.5 | 1–4 |
| 1d4+1 (magic missile dart) | 3.5 | 2–5 |
| 2d4+2 (healing potion) | 7 | 4–10 |
| 3 darts (3d4+3) | 10.5 | 6–15 |
Bless adds an average of +2.5 to every attack and save — statistically stronger than a +2 bonus, and one of the best 1st-level buffs in the game.
D4 Roller FAQ
How do you read a d4?
A d4 lands with a point (or an edge) up rather than a face. On point-up sets, read the number at the top vertex; on base-up sets, read the number sitting upright along the bottom edge. All three visible sides show the same result.
What is the average roll of a d4?
The average of one d4 is 2.5, since faces 1 through 4 are equally likely. A magic missile dart (1d4+1) averages 3.5, and a healing potion (2d4+2) averages 7.
Is Bless better than a +2 bonus?
On average, yes. Bless adds 1d4 — an average of +2.5 — to every attack roll and saving throw, and unlike a flat +2 it can swing a roll by up to 4 points.
