The Tabletop Polyhedral Dice Set

Every tabletop roleplaying game relies on a seven-piece polyhedral set. Each geometric shape serves a specialized role during gameplay sessions:

  • d4 (Tetrahedron): Small weapons (daggers, clubs), healing potions, and spells like Magic Missile.
  • d6 (Cube): Shortswords, bows, handaxes, and area-of-effect spells such as Fireball (8d6).
  • d8 (Octahedron): Standard martial weapons (longswords, rapiers) and moderate healing spells.
  • d10 & d100 (Decahedron / Percentile): Heavy polearms, cantrips like Eldritch Blast, and percentile wild magic tables.
  • d12 (Dodecahedron): Mighty weapons like greataxes and Barbarian class hit dice.
  • d20 (Icosahedron): All checks, attacks, saving throws, and skill contests.

Rolling Character Ability Scores (4d6 Drop Lowest)

When rolling a new character sheet, the classic method for determining Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma is rolling four six-sided dice and discarding the lowest value (written as 4d6kh3 or "4d6 drop lowest").

Our roller supports this syntax natively. Type 4d6kh3 into the notation box and press Roll. You will see all four rolls rendered, with the lowest rolled die automatically struck out and excluded from your total score.

Saving Custom Attack and Spell Presets

During active combat encounters, repeatedly typing expressions like 1d20+6 for an attack roll followed by 2d6+4 for greatsword damage can slow down your turn. Open the Presets tab in the bottom sheet to store your character's signature maneuvers. Load them with a single click whenever your turn arrives in the initiative order.

Frequently Asked Questions

How do I roll character ability scores here? ↓

Simply enter 4d6kh3 into the notation input. This rolls 4 six-sided dice, keeps the highest 3, and displays which die was dropped.

Are digital dice fair compared to physical resin dice? ↓

Yes, and often superior. Physical acrylic dice frequently contain interior air bubbles or uneven tumbling edges that cause microscopic weight imbalances. Our CSPRNG rejection-sampling algorithm guarantees zero modulo bias across every roll.

How do advantage and disadvantage rolls work for d20 checks? ↓

When rolling with advantage, two d20 dice are rolled and the higher result is used. With disadvantage, the lower result is used. You can toggle advantage and disadvantage with one click above the dice or type d20 adv and d20 dis directly.
