1. What is Dice Rolling in DnD 5e?

Dice rolling is fundamental to Dungeons & Dragons 5th Edition gameplay. It determines the outcomes of actions, attacks, damage, and random events. The standard notation is (number of dice)d(dice type)+(modifier).

2. How Does the Calculator Work?

The calculator simulates dice rolls using the formula:

Where:

• \( n \) — Number of dice rolled
• \( d \) — Dice type (4, 6, 8, 10, 12, 20, or 100)
• \( \text{modifier} \) — Number added to the total

Explanation: For each die, a random integer is generated between 1 and the dice type. All dice results are summed and the modifier is added.

3. Common Dice Types

Standard Dice:

• d4 - Pyramid-shaped die
• d6 - Standard cube die
• d8 - Octahedral die
• d10 - Pentagonal trapezohedron
• d12 - Dodecahedral die
• d20 - Icosahedral die (most common for ability checks)
• d100 - Typically rolled as two d10s (percentile dice)

4. Using the Calculator

Tips: Enter the number of dice (1-100), select the dice type (d4-d100), and add any modifier. Common examples: "1d20+5" for an attack roll or "2d6+3" for greatsword damage.

5. Frequently Asked Questions (FAQ)

Q1: What does "advantage" mean in DnD 5e?
A: When you have advantage, you roll 2d20 and take the higher result. Disadvantage means rolling 2d20 and taking the lower result.

Q2: What's the most common roll in DnD?
A: The d20 is most common for ability checks, attack rolls, and saving throws. Damage rolls use other dice depending on weapons/spells.

Q3: How do critical hits work?
A: On a natural 20 attack roll, you roll all damage dice twice (or double the number of dice) and add modifiers once.

Q4: What's the average result for common dice?
A: Average = (dice type + 1)/2. So d6 averages 3.5, d20 averages 10.5, etc.

Q5: Can I roll multiple dice types at once?
A: This calculator handles one type at a time. For mixed rolls (like 1d8+2d6), you'd need to calculate each type separately.
