I’ve actually managed to spend some hours on the project again … not much progress, but still. I’ve managed to give magic items color hues. So far I’ve defined:
add life - yellowish green
add mana - blue
add damage - orange
add defense - brown
resist fire - red
resist ice - cyan
resist lightning - yellow
resist poison - blueish green
resist fear - white
resist confusion - purple
Also I’ve been adding some environmental stats. Part of the values is natural for the place, but they can be altered by spells (eg. cold + humid + fireball -> hot + dry)
Temperature
Ground status: solid dry, solid moist, swamp, water, ice, lava …
Static: Uncharged, Charged, Highly charged, Sparking …
Air: Dry, humid, dusty, steamy …
The exact conditions may change. This is just a design sketch so far, somewhat matching the elemtal magic effect of fire, ice, lightning.
