## Loot 2.0 Armor Changes (VU 15.15, June 2017)

MindArk made significant changes to how armors work:

### Key Changes:
1. **Armor decays significantly less** per point of damage absorbed
2. **No minimum decay** based on total protection - always proportional to damage absorbed
3. **Armor absorbs ALL incoming damage** - no more 1.0 damage taken on full absorption (shown as "Deflected" message)
4. **Armor and platings decay independently** based on actual damage each absorbs, not both decaying as if absorbing full damage
5. **Armor decay is now linear** per point of damage absorbed (not increasing cost per damage)

---

## Armor Economy (Durability)

### Base Protection Cost:
**20 hp / pec** - This is the standard armor durability baseline.

### Comparison with Healing Tools:
| Protection Method | Economy |
|-------------------|---------|
| Armor (base) | ~20 hp/pec |
| EMT Kit Ek-2600 Improved | 20 hp/pec |
| Refurbished H.E.A.R.T Rank VI | 18 hp/pec |
| Vivo S10 | 12.31 hp/pec |
| Herb Box | 10.06 hp/pec |
| EMT Kit Ek-2350 | 4 hp/pec |

**Conclusion:** Armor is very economical compared to most healing tools.

## Armor Progression Guide

### 1. First Armor: Graduation Set
- Get by graduating with a Mentor
- Each planet has unique graduation armor
- **Best choice:** Atlas (NI) or Musca Adjusted (Arkadia)

### 2. Early Game: Before Ghost
**Add plates first!** Get 5B plates for your graduation armor.

Then choose:
- **Gremlin** - Most versatile armor
- **Nemesis** - Upgradeable to Adjusted Nemesis (robot armor)
- **Ghost** - Most protection for the money (recommended)

### 3. Mid Game: After Ghost+5B
Options (price jump!):
- **Adjusted Nemesis** (~2.5k PED) - Good for robots
- **Lion** (~5-6.5k PED) - Robot Beacon drops
- **Adjusted Boar** (~7.5-9.5k PED) - 30 Impact, Dodge buff
- **Looted (L) pieces** - Cheap bridge option

### 4. End Game
- Upgraded Angel
- Upgraded Gorgon
- Modified Viceroy (avatar bound, ~9k PED)

## Damage Absorption Mechanics (Post-Loot 2.0)

### How Protection Works:
1. **Plate takes damage first** (if equipped)
2. **Armor takes remaining damage**
3. **Player takes overflow** (if any)

### Decay Calculation:
```
Plate decay = (damage_absorbed_by_plate / total_plate_protection) × plate_decay_rate
Armor decay = (damage_absorbed_by_armor / total_armor_protection) × armor_decay_rate
```

**Key Point:** Plate and armor decay **independently** based on actual damage each absorbs.

### Example:
- Monster hits: 20 Impact damage
- Plate protects: 15 Impact
- Armor protects: 5 Impact (remaining)
- Player takes: 0 damage (deflected)

**Decay:**
- Plate decays for absorbing 15 damage
- Armor decays for absorbing 5 damage

---

## Armor Buffs

Many armor sets offer buffs:
- **20% increased Dodge chance**
- **10-20% increased Evade chance**
- **3% faster reload speed**
- **5% Acceleration**
- **1-4% Block chance**
- Heal over time

**Block Chance:** Some upgraded plates have Block Chance - when triggered, hit is nullified (no damage, no decay).

## Armor Sets Reference

### Entry Level:
- **Gremlin** - Most versatile early armor
- **Ghost** - Best protection for price
- **Nemesis** - Robot hunting, upgradeable

### Mid Level:
- **Adjusted Nemesis** - Robot specialist
- **Lion** - Stab-focused protection
- **Adjusted Boar** - 30 Impact, Dodge buff

### High Level:
- **Angel** (upgraded)
- **Gorgon** (upgraded)
- **Modified Viceroy** (avatar bound)

---

## Plating Strategy

### General Rule:
- **5B plates** are the standard early-game addition
- Match plates to mob's damage type
- All 7 plates should match (don't mix types)

### Plate Types:
- **5B** - General purpose (Impact/Stab/Cut)
- **6A** - Cold/Electric protection
- **5C** - Burn/Acid protection
- Custom plates for specific mobs

## Implementation Notes for Lemontropia Suite

1. **Decay Formula:** Linear per damage point absorbed
2. **Plate Priority:** Plates absorb first, then armor
3. **Independent Decay:** Each piece decays separately
4. **Deflected Message:** Indicates full absorption (0 player damage)
5. **Block Chance:** Roll for block before applying damage
6. **Protection Stacking:** Plate + Armor protection values add

---

## Key Formulas

### Cost Per Hit:
```
armor_cost = (damage_absorbed_by_armor / armor_protection) × armor_decay_per_pec
plate_cost = (damage_absorbed_by_plate / plate_protection) × plate_decay_per_pec
total_cost = armor_cost + plate_cost
```

### Protection Calculation:
```
total_protection = armor_protection + plate_protection
if total_protection >= damage:
    player_damage = 0
    absorbed_by_plate = min(damage, plate_protection)
    absorbed_by_armor = damage - absorbed_by_plate
else:
    player_damage = damage - total_protection
    absorbed_by_plate = plate_protection
    absorbed_by_armor = armor_protection
```
