Frequently Asked Questions — D10 Dice Roller
Complete guide to the D10 ten-sided die for RPGs and percentile rolls
What is a D10 die?
A D10 is a 10-sided pentagonal trapezohedron die numbered 1-10 (or 0-9). It's one of the standard polyhedral dice used in RPGs, and two D10s can be combined to roll percentile dice (D100).
How do percentile dice work with a D10?
Percentile dice use two D10s: one designated as the "tens" die (showing 00, 10, 20...90) and one as the "units" die (showing 1-10/0). You combine the results — e.g., tens shows 30 and units shows 7 = result is 37. A roll of 00 and 0 together equals 100.
What classes use D10 hit dice in D&D 5e?
In D&D 5e, the Fighter and Paladin classes use D10 hit dice, making them among the toughest adventurers. This means they gain 10 maximum hit points per level (plus Constitution modifier), plus roll D10 when gaining levels.
What weapons deal D10 damage?
D10 weapons in D&D 5e include the heavy crossbow, glaive, halberd, pike (when used with Great Weapon Master), and the longsword/battleaxe/warhammer when wielded two-handed. The D10 also represents the "Great Weapon" style damage tier.
How does the D10 work in Vampire: The Masquerade?
In Vampire: The Masquerade, players roll pools of D10 dice and count "successes" (usually 6, 7, 8, or 9+ depending on edition). The number of successes determines the degree of success or failure. This makes D10 pools the core mechanic.
What is the average of a D10 roll?
The average of a D10 roll is 5.5. Each outcome from 1-10 has a 10% probability, so the expected value is (1+2+...+10)/10 = 55/10 = 5.5.
What is the shape of a D10?
A D10 is a pentagonal trapezohedron — not one of the five Platonic solids. It has 10 kite-shaped faces arranged in two groups of 5, meeting at a shared edge band around the middle. This gives it its distinctive elongated shape.
How is D10 used in other game systems?
Beyond D&D, D10s are core to World of Darkness games (Vampire, Werewolf, Mage), Storyteller System games, GURPS uses D6 but many supplements use D10, and Exalted uses large pools of D10s. It's one of the most versatile RPG dice.
Can I roll D10 for coin flip decisions?
Yes! Assign 1-5 to one outcome and 6-10 to another for a 50/50 decision. Or use 1-3, 4-6, 7-9 for three equal options (treating 10 as a reroll). The D10's 10% increments make probability math easy.
What is a D10 used for in crits and fumbles?
Some game systems use D10 to determine the severity of critical hits or critical failures. A D10 result of 1-3 might be minor, 4-7 moderate, and 8-10 catastrophic. This creates more nuanced outcomes than a simple pass/fail.
