## Weapon tier ##
Natural / Common Stone -> Copper -> Iron -> Silver -> Titanium
Forging --------------> Steel --------^
Exotic ('elven') Glass Aurichalcum
Special (something 'adamant') ??? (Use material spec of CNT, tensile strength 180 GPa)
* Metal graphics
- Gold: Hue 43, low Saturation
- Aurichalcum: Hue 43, mid-high Saturation
- Copper: Hue 33,
- Copper rust: Hue 160
- Iron rust: Hue 21
## Size variation ##
Race base weapon/tool size <- 10 [kg]
Size tolerance <- (50% * str/1000), or say, 20%
If the size is bigger than tolerable, weapon speed severely slows down, tools become unusable
if use time >* 0.75 second, the weapon/tool cannot be equipped.
Small weapons/tools gains no (dis)advantage
When drawing: scale by (craftedWeaponSize / baseWeaponSize)
Crafted tool/weapon size is dependent to the baseRaceMass.
## Gemstone tier ##
Topaz -> R·G·B -> Diamond·Amethyst
## Colouring ##
Natural: Use 4096
Magical/Surreal: Use 24 Bits
* Colouring of potion
- Randomised, roguelike fashion
- Choose Col(R40, G40, B40) from set of finite cards:
39, 39, 19, 19, 0, 0
- MULTIPLY blend chosen colour with white texture
## Roguelike identity ##
* Randomised things
- E.g. potion
Lime-coloured potion
First play: "Potion (???)"
After drank: "Potion (Healing)" is revealed.
Second (new) play: "Potion (???)"
After drank: "Potion (Neurotoxin)" is revealed.

## (De)serialisation ##
see SAVE_FORMAT.md
## Actor as universal tool ##
* Utility tiles that have states (e.g. noteblock) are implemented using Actor.

* AI:
Attacked first: Warn player to not attack
Attacked second: The NPC becomes hostile until player sheathe the weapon
Attacked thrice: All the NPCs within the same faction become hostile until the player is away
## Ownership of lands ##
* Codex of Real Estate → assign owner to the tiles → copy the information to the NPC instance
## Health and magic point ##
* Works like Ampere in electronics.
