Roles of Gems in Magic

Some spells, especially those powerful, require the energy contained in precious gems to trigger them. To invoke such spell, the player must have a pirate with certain skills, and must also possess a gem of a certain type while casting the spell.

The spell, during its creation, draws energy from the gem, dispersing it and changing its physical structure. Because of this, the gem is destroyed with the invocation of the spell.

Before casting a spell that requires a gem, the player must reconfirm the desire to cast it.
