Arms of God Blessing Math Guide — How Stacking & Multipliers Actually Work
Why Blessing Math Matters
"Fire Affinity: +25% Fire damage" — sounds simple. But paired with "Inferno: +10% damage to burning enemies" and "Amplified Fire: +50% to fire effects" — what's your actual DPS? The answer depends on whether these stack additively or multiplicatively.
Additive vs Multiplicative
Additive Stacking (most +% blessings)
```
Final Damage = Base × (1 + 0.25 + 0.10 + 0.50)
= Base × 1.85
```
All three blessings combined = 85% total increase. Each additional blessing adds less RELATIVE value.
Multiplicative Stacking (rare blessings)
```
Final Damage = Base × 1.25 × 1.10 × 1.50
= Base × 2.0625
```
Same numbers, but 106% total increase vs 85%. The difference grows with each blessing.
Which Blessings Are Which
| Type | Stacking | Examples |
|------|----------|---------|
| Element Affinity | Additive | Fire/Holy/Shock/Dark Affinity |
| Conditional damage | Multiplicative | "to burning enemies", "to frozen enemies" |
| Crit damage | Multiplicative | Always separate multiplier |
| Attack speed | Additive with itself, multiplicative with damage | Swift Hands, Haste |
| Damage reduction | Additive (capped at 60%) | Iron Will, Fortress |
The Optimization Formula
To maximize DPS, balance additive and multiplicative sources:
```
Optimal: (additive_sum) ≈ (multiplicative_count × 0.25)
```
Rough rule: For every +100% additive damage, you want at least one multiplicative source.
Soft Caps & Diminishing Returns
- Damage reduction: hard capped at 60%
- Attack speed: soft cap at +50% (diminishing returns after)
- Crit chance: hard cap at 100% (excess converts at 2:1 to crit damage with Critical Overflow)
- Lifesteal: no cap but diminishing returns on healing past max HP
Practical Takeaway
Don't stack 5 "+% Fire damage" blessings. Get 2, then look for multiplicative sources like "to burning targets" or crit damage. The difference between 185% and 206% is 21% — that's an entire extra blessing's worth of damage.
