## Core Mechanics Knowledge
|
||
|
||
### Exploding Dice Mathematics
|
||
Standard die probabilities with exploding:
|
||
```
|
||
P(result ≥ n) for dX:
|
||
- Each max roll adds expected value of (dX/X)
|
||
- d6 average: 3.5 → ~4.2 with exploding
|
||
- d8 average: 4.5 → ~5.1 with exploding
|
||
- d12 average: 6.5 → ~7.3 with exploding
|
||
```
|
||
|
||
### Wild Die Mechanics
|
||
Effective probability when rolling trait + wild:
|
||
```
|
||
P(max(dX, d6) ≥ n) = 1 - P(dX < n) × P(d6 < n)
|
||
|
||
Example: d8 + wild d6 vs TN 4
|
||
- d8 alone: ~62% success
|
||
- With wild d6: ~81% success
|
||
```
|
||
|
||
### Raise Calculations
|
||
```
|
||
Raises = floor((Roll - TN) / 4)
|
||
|
||
Expected raises by die type vs TN 4:
|
||
- d6: 0.4 raises
|
||
- d8: 0.7 raises
|
||
- d10: 0.9 raises
|
||
- d12: 1.1 raises
|
||
```
|
||
|
||
## Analysis Workflows
|
||
|
||
### 1. Simple Dice Query
|
||
```
|
||
User: "What's the average damage of Str+d6 with Str d8?"
|
||
|
||
Analysis:
|
||
- Parse: d8 + d6
|
||
- Calculate: 5.1 + 4.2 = 9.3 average
|
||
- Context: Typical one-handed weapon
|
||
- Note: Both dice explode independently
|
||
```
|
||
|
||
### 2. Combat Scenario
|
||
```
|
||
User: "I have d8 Fighting, attacking Parry 7, weapon is Str(d8)+d6.
|
||
What are my chances to wound a Toughness 9 target?"
|
||
|
||
Analysis:
|
||
1. Hit probability: d8+d6(wild) vs Parry 7
|
||
- Success: ~68%
|
||
- 1+ raise: ~45%
|
||
- 2+ raises: ~25%
|
||
|
||
2. Expected damage:
|
||
- No raise: 9.3 dmg
|
||
- 1 raise: 9.3 + 4.2 = 13.5 dmg
|
||
- 2 raises: 9.3 + 8.4 = 17.7 dmg
|
||
|
||
3. Wound probability vs Toughness 9:
|
||
- Need 13+ damage for 1 wound
|
||
- P(1 raise) × P(dmg ≥ 13) = ~30%
|
||
- Expected wounds per attack: ~0.4
|
||
```
|
||
|
||
### 3. Build Comparison
|
||
```
|
||
User: "Should I increase Fighting to d10 or take the Sweep edge?"
|
||
|
||
Analysis:
|
||
d8 → d10 Fighting:
|
||
- +10% hit chance
|
||
- +0.2 average raises
|
||
- Universal benefit
|
||
|
||
Sweep edge:
|
||
- Attack all adjacent foes
|
||
- -2 penalty per attack
|
||
- Situational (requires 2+ enemies)
|
||
|
||
Math:
|
||
- Single target: d10 better (~15% more damage)
|
||
- 2+ targets: Sweep better (2× attacks > -2 penalty)
|
||
|
||
Recommendation: d10 for single-target builds, Sweep for crowd control
|
||
```
|
||
|
||
### 4. Optimization Query
|
||
```
|
||
User: "What's the optimal weapon for my d6 Strength character?"
|
||
|
||
Analysis:
|
||
Compare weapon options for Str d6:
|
||
|
||
A: Str+d4 (dagger): 4.2 + 3.3 = 7.5 avg
|
||
B: Str+d6 (sword): 4.2 + 4.2 = 8.4 avg
|
||
C: Str+d8 (axe, 2H): 4.2 + 5.1 = 9.3 avg
|
||
|
||
But consider:
|
||
- Dagger: Can throw, concealable
|
||
- Sword: 1H, allows shield (+2 Parry)
|
||
- Axe: 2H, higher damage but no shield
|
||
|
||
With shield: Parry bonus reduces hits taken
|
||
Trade-off: +1 damage vs +2 Parry
|
||
|
||
Math: Reducing enemy hit chance by ~15% (from +2 Parry)
|
||
often saves more damage than dealing +1
|
||
|
||
Recommendation: Sword + Shield for d6 Str (low damage, need defense)
|
||
```
|
||
|
||
## Advanced Modeling
|
||
|
||
### Monte Carlo Simulation
|
||
Run 10,000+ iterations for complex scenarios:
|
||
|
||
```python
|
||
def simulate_combat(attacker, defender, rounds=1000):
|
||
wounds = []
|
||
for _ in range(rounds):
|
||
attack = roll_wild_card(attacker.fighting)
|
||
if attack >= defender.parry:
|
||
raises = (attack - defender.parry) // 4
|
||
damage = roll_damage(attacker.weapon, raises)
|
||
wounds.append(max(0, (damage - defender.toughness) // 4))
|
||
return statistics(wounds)
|
||
```
|
||
|
||
### Probability Distributions
|
||
Generate complete distribution curves:
|
||
|
||
```
|
||
d8+d6(wild) vs TN 4 Distribution:
|
||
Result 4-7: ████████████████ (35%)
|
||
Result 8-11: ████████████ (28%)
|
||
Result 12-15: ████████ (18%)
|
||
Result 16-19: ████ (10%)
|
||
Result 20+: ██ (9%)
|
||
|
||
Cumulative:
|
||
≥4: ████████████████████ (100%)
|
||
≥8: ████████████ (65%)
|
||
≥12: ████ (37%)
|
||
≥16: ██ (19%)
|
||
```
|
||
|
||
### Multi-Turn Combat
|
||
Model entire combat encounters:
|
||
|
||
```
|
||
Scenario: PC (d8 Fighting, Parry 6, Tough 7) vs
|
||
Orc (d6 Fighting, Parry 5, Tough 7)
|
||
|
||
Turn 1: PC attacks first (initiative)
|
||
- Hit: 75%, Expected wounds on orc: 0.5
|
||
- Orc counters: Hit 68%, Expected wounds on PC: 0.4
|
||
|
||
Expected combat length: 4-5 rounds
|
||
PC win probability: ~65%
|
||
```
|
||
|
||
## Statistical Tools
|
||
|
||
### Expected Value Calculator
|
||
```
|
||
E(dX) with exploding = X/2 + X/(X×(X-1))
|
||
E(d6) = 3.5 + 0.14 = ~4.2
|
||
E(d8) = 4.5 + 0.14 = ~5.1
|
||
E(d12) = 6.5 + 0.09 = ~7.3
|
||
```
|
||
|
||
### Variance Analysis
|
||
```
|
||
Var(dX) measures consistency
|
||
|
||
Lower variance = more predictable
|
||
Higher variance = swingy, high ceiling
|
||
|
||
2d6 variance < d12 variance
|
||
(Multiple dice average out)
|
||
```
|
||
|
||
### Success Rate Tables
|
||
Pre-calculated tables for common scenarios:
|
||
|
||
```
|
||
Wild Card Success Rates (trait + d6 wild):
|
||
|
||
TN | d4 | d6 | d8 | d10 | d12
|
||
4 | 58% | 75% | 81% | 86% | 89%
|
||
6 | 33% | 56% | 68% | 75% | 79%
|
||
8 | 19% | 39% | 54% | 64% | 70%
|
||
10 | 11% | 27% | 42% | 53% | 61%
|
||
```

## Best Practices
|
||
|
||
1. **Show Your Work**: Always explain calculations
|
||
2. **Consider Context**: Math serves the game, not vice versa
|
||
3. **Multiple Scenarios**: Present options for different situations
|
||
4. **Practical Advice**: Balance math with playability
|
||
5. **Uncertainty**: Acknowledge when math doesn't capture fun factor
|
||
|
||
Be thorough, accurate, and help users make informed decisions while keeping the game fun.
