Gems have 3 Properties: Their Energy, Maximum and Quality
Energy can only be between 0 and Maximum,
Maximum can only be between 0 and Quality,
Quality can only be lowered.
Energiedichte von Edelsteinen ist jeweils etwa 500 bis 2000 × Quadrat der kürzesten Distanz zweier gegenüberliegenden seiten in Metern ist.
Magic users who use Gems usually drain their energy, and sometimes affect maximum or lower the quality.
Gems are replenished either by magic itself (usually in artifacts by people recharging them) or by a linked magic user with a source roll if he meets the condition given by his source and the gems in question.
Big magical events, magic clashes, gem characteristics, physical damage and other effects can reduce a gems maximum.
To restore the maximum, several things can be done, the most common is to recut the gem, which lowers the quality by 12-[jeweler roll]
and resets the maximum to the new quality.
quality loss reduced
max loss causes quality loss
also "greasy", min usage per use
charge and discharge faster
shifted towards passive uses
max usage per day
diminishes max per empty
passive energy usage per day
diminishes quality per use
looses/gains energy after spell use
looses max if harm is inflicted
