## 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%
```
