# item-power-calculator
A containerized, web-based tool for calculating the power level of items in Acropolis. This calculator helps builders design balanced items and allows players to evaluate their loot's relative power.
## Purpose
The calculator provides a standardized way to measure and compare the power level of items in Acropolis. It uses a formula that takes into account various item attributes, including:
- Basic stats (HR, DR, saves)
- Attributes (STR, DEX, CON, INT, WIS, CHA)
- Resource bonuses (HP, MANA, MOVE)
- Resistances
- Spell effects and casts
- Meta-stats (crit chance, penetration, etc.)
- Weapon-specific attributes (damage dice, special types)
- Armor-specific attributes (AC values)
## Power Score Formula
### Common Terms
- **HR, DR**: Hit Roll and Damage Roll (positive integers)
- **saves**: A single "Saves" value
- Negative saves (e.g. -15) are beneficial and add |saves| to PS
- Positive saves are detrimental and subtract from PS
- **Attributes**: STR, DEX, CON, INT, WIS, CHA (+2 PS per point)
- **Resources**: HP, MANA, MOVE (+0.1 PS per point)
- **Specific Resistances**: Each resistance (fire, cold, etc.) = +10 PS
- **Spellaffects**: +15 PS each
- **Spellcasts**: +20 PS each
### Meta-stats (Raw Values)
Meta-stats are entered as raw values and converted to percentages (raw/100) before being weighted:
```
Crit Chance: raw/100 × 10 PS per 1%
Crit Damage: raw/100 × 8 PS per 1%
Penetration: raw/100 × 5 PS per 1%
Recuperation: raw/100 × 2 PS per 1%
Concentration: raw/100 × 2 PS per 1%
Endurance: raw/100 × 2 PS per 1%
Prosperity: raw/100 × 1 PS per 1%
```
### Weapon Power Score (PS_W)
```
PS_W =
HR
+ DR
+ saves (negative adds |saves|, positive subtracts |saves|)
+ 2 × (STR + DEX + CON + INT + WIS + CHA)
+ 0.1 × (HP + MANA + MOVE)
+ 10 × (count of specific resistances)
+ 15 × (number of spellaffects)
+ 20 × (number of spellcasts)
+ 0.5 × AvgDamage
+ Σ(Special Types PS)
+ Meta-stats contributions
```
Where:
- **AvgDamage** = X × (Y + 1)/2 for "Damage is X d Y"
- **Special Types PS**:
- Flaming: +10 PS
- Frost: +10 PS
- Shocking: +10 PS
- Acid: +10 PS
- Vampiric: +15 PS
- Vorpal: +10 PS
- Purify: +10 PS
- Sharp: +10 PS
- Twohands: -20 PS (requires both hands)
- Poison: +10 PS
### Armor Power Score (PS_A)
```
PS_A =
HR
+ DR
+ saves (negative adds |saves|, positive subtracts |saves|)
+ (AC_pierce + AC_bash + AC_slash + AC_exotic)
+ 2 × (STR + DEX + CON + INT + WIS + CHA)
+ 0.1 × (HP + MANA + MOVE)
+ 10 × (count of specific resistances)
+ 15 × (number of spellaffects)
+ 20 × (number of spellcasts)
+ Meta-stats contributions
```
## Example Calculation
### Bloodstone Axe of Power
```
Damage: 16d15
→ AvgDamage = 16 × (15+1)/2 = 128
→ WeaponDmgPS = 0.5 × 128 = 64
Special Types:
- Flaming (+10)
- Vampiric (+15)
- Acid (+10)
- Shocking (+10)
Total: 45 PS
Stats:
- HR: +13
- DR: +13
- HP: +100 (10 PS)
- Spellcast(cause_critical): +20 PS
- Saves: 0 (no impact)
Final PS_W = 13 + 13 + 0 + 0 + 10 + 0 + 0 + 20 + 64 + 45 = 165
```
## Usage
1. Select item type (Weapon or Armor)
2. Enter all relevant stats and attributes
3. For weapons, specify damage dice and special types
4. For armor, enter AC values
5. Add any resistances, spell effects, or meta-stats
6. The calculator will automatically compute the final Power Score
## Quest Items
All values are rounded to two decimals.

The "nine inch nail" is an anomaly due to its high hp and mana stats.
