Homebrew Natural armor in Daggerheart - Full test info

# Homebrew Natural armor in Daggerheart

DnD playable race Lizardfolk is from Mordenkainen Presents.
They have natural armor when no armor is worn: AC=13+dex

Here I have tried to homebrew something that's not a game breaking feature.
TODO: solo play testing

It's also possible I have bugs in my testing methodology or I've misunderstood some rule, lemme know!
### Resilient hide
Mechanically: On average Resilient is comparable to gambeson and stronger when paired with proficiency perks from level up. Better evasion from low damage, more vulnerable to major/massive damage.

Without armor you are an easier target but your hide has a higher chance deflecting minor attacks.
Evasion: Class evasion + Proficiency + 1

**Natural armor**:
Tier n:
Base score: 3+n
Base thresholds:
	minor 4+2\*n
	major 1+7\*n

Tier 1: bt 4/8    , bs 4
Tier 2: bt 6/15  , bs 5
Tier 3: bt 8/22  , bs 6
Tier 4: bt 10/29, bs 7

**Mechanically**: Armor repairing works the same, thematically the body is quick to recover.

**Resilient** is a good supporting ancestry as Severe damage is likelier due to lower major threshold, though it costs stress

(Original Daggerheart ancestry for reference)
### Scales
Your scales act as natural protection. When you would
take Severe damage, you can mark a Stress to mark 1 fewer
Hit Points.

#### Python simulate armor
Compare Natural armor to other armor types

100000 simulations of Tier 1-4 monsters
- NPC Damage die vs PC Evasion/Armor threshold,
- Only NPC basic hits were simulated
- Typeless dmg, Tank test solo, No player actions

Tested PC level/armor tier vs NPC tier
lv1 vs Tier 1
lv5 vs Tier 3
lv10 vs Tier 4

The simulated player uses reaction to use up all armor and stress till it reaches 0 hit points
Score is calculated by averaging hit counts between all scenarios: Every armor vs every monster hit die.
Higher score is better.


**Advancements:**
```
level: chosen level up perks
1:  -
2:  hp trait
3:  hp stress
4:  stress evasion*
5:  proficiency*
6:  hp trait
7:  stress evasion*
8:  proficiency*
9:  hp trait
10: stress evasion*

"Score Less optimal" excludes perks marked with '*' (asterisk)
This is for testing how the score behaves with different builds, e.g. swap to cards/traits/experience
```


**Level up breakdown**:
```
class: (Custom Codex-Midnight)
hp: 4
stress: 6
evasion (natual) = evasion + proficiency + 1
evasion (gambeson) = evasion + 1

lv : stats summed
1:   hp:4 stress:6 eva:14 prof: 1
2:   hp:5 stress:6 eva:14 prof: 1
3:   hp:6 stress:5 eva:15 prof: 1
4:   hp:6 stress:7 eva:15 prof: 1
5:   hp:6 stress:7 eva:16 prof: 2
6:   hp:7 stress:7 eva:17 prof: 2

10:  hp:8 stress:9 eva:19 prof: 3
Gambeson = 12+eva+1
```
