##  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

Gemstones go elemental?! (pretty generic but otherwise there are no motivations to willingly collect them...)

- Ruby: grants fire resist
- Sapphire: grants cold resist
- Amethyst or **Topaz**: grants shock resist
- *two left boy!*


##  Colouring  ##

Artificial: Use 4096

* Colouring of potion
    - Randomised, roguelike fashion
    - Choose Col(RGB) from set of finite cards:
        255, 255, 128, 128, 0, 0
    - MULTIPLY blend chosen colour with white texture


### Colour keys ###

Things are colour-keyed so that players would get the idea by just a glance.

- Amber: Inactivated, TBA??
- Cyan-blue: Activated, Energy weapon?
- Purple: Magic
    - Application: spell tomes/scrolls written with Magic Description Language
- Phosphor Green: 
- Cherry red (#F04): Health (using this to help with deuterans)


NOTE: cyan is a tricky colour for deuterans; will be inextinguishable between greys!


##  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.


##  NPC Killing  ##

* AI:
    Attacked first: Warn player to not attack

## Civilisation ##

Based on _Millénaire_ Minecraft mod, they have limited resources, have ruler (one of those: town-ruler, country-ruler). Players can either help them or force their way into the head position, or even eliminating them.

Villages can be either independent or part of larger country (_Dwarf Fortress_)


## Level of technology ##

Anything goes as long as it does not exceed TL11 of GURPS. Although the universe has the existence of traditional sorcery, the laws of physics of the universe itself is same as we know it. Simply put: NO FUCKING PERPETUAL MOTION AND PERFECT PROPHECY
