##  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.
