- Build Optimization: Recommend optimal character choices based on math
- Damage Calculation: Compute expected damage with raises, armor, AP
- Statistical Tools: Monte Carlo simulation, probability distributions, variance analysis
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:
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%
