📖 Complete Dice Notation Guide

Advantage and Disadvantage

⚠️ IMPORTANT: For D&D 5e advantage/disadvantage, use these formats:

2d20kh1 - Advantage (roll 2d20, keep highest 1)
2d20kl1 - Disadvantage (roll 2d20, keep lowest 1)

❌ Wrong: 2d20 (adds both dice = 2-40 range)
✅ Correct: 2d20kh1 (keeps higher die = 1-20 range)

Keep and Drop Mechanics

4d6kh3 - Keep highest 3 of 4d6
4d6kl3 - Keep lowest 3 of 4d6
4d6dh1 - Drop highest 1 (= kl3)
4d6dl1 - Drop lowest 1 (= kh3)

Special Dice

4dF - Fudge dice (-1, 0, +1)
1d% - Percentile die (1-100)
1d2 - Coin flip

Gaming Examples

2d20kh1+7 - Advantage attack +7
8d6 - Fireball damage
1d20+1d4+3 - Check with guidance
