Hit Dice Formula Explained
The Hit Dice system follows a simple but powerful formula.
1. HP per Level Formula
HPper level=Hit Die+Constitution Modifier
This formula calculates how much HP a character gains per level.
2. Maximum HP Formula
Max HP=(Hit Die+Constitution Modifier)×Level
This shows total HP gained across all levels.
3. Total HP Formula
Total HP=Current HP+Max HP
This includes existing HP plus newly calculated HP.
Example Calculation (Step-by-Step)
Let’s understand with a real example.
Character Details:
- Level: 5
- Hit Die: d8 (8)
- Constitution Modifier: +2
- Current HP: 10
Step 1: HP per Level
8 + 2 = 10 HP per level
Step 2: Maximum HP
10 × 5 = 50 HP
Step 3: Total HP
50 + 10 = 60 HP total
Example Table for Better Understanding
| Level | Hit Die | CON Mod | HP per Level | Max HP |
|---|---|---|---|---|
| 1 | 8 | +2 | 10 | 10 |
| 3 | 8 | +2 | 10 | 30 |
| 5 | 10 | +3 | 13 | 65 |
| 10 | 12 | +2 | 14 | 140 |
| 15 | 10 | +1 | 11 | 165 |
