Magic and Runes
Legend of Grimrock has a rune-based spellcasting system where all the spells are described as a combination of runes. Each of the magical runes represents a different concept, like an element or a force of the physical or immaterial world, and different combinations of these concepts are used to form spells. In addition to knowing the combination of the runes, the spellcaster needs to be skilled enough in the school of magic a spell requires to cast it. Scrolls describing different rune combinations can be found in the dungeons but a resourceful wizard may discover some by experimenting.
FIRE. The first rune is fire, one of the elements. Elements are a major group in the runes. There are four elements and all of them reside in the corners of the pattern. Fire magic is very suitable for destructive powers and fire is the rune of strength.
LIFE. This rune represents health, bravery, creation and light. It is a common rune in spells that aid and assist but it can also be used in creating or modifying matter. Life is the opposing force of death.
AIR. The element of air not only covers the air that we breathe but also the sky, storms and gases. It is also often used in conjunction with other less buoyant elements to help them float or fly and air is the rune of dexterity.
SPIRITUALITY. This rune represents the immaterial world: the things that have no matter but which still exist. It is used for invoking the forces of the mind, thought and spirituality. It is useful in spells that either enhance or disrupt the psyche
of beings or to surpass the barriers of mundane senses.
BALANCE. This is the central rune that all the other runes are bound to and it has no opposite. It represents everything, wholeness and unity. The invisible force that binds everything together while keeping them apart. Mortal spellcasters can only exploit a tiny sliver of the vast potential of this force and they usually use it to amplify their spells to affect larger wholes.
PHYSICALITY. This represents the material world and strong physical forces. It helps otherwise immaterial things attain a more stable physical form or adds to the strength of otherwise weak phenomena. Physicality is the opposing force of spirituality.
EARTH. A strong and stable element, earth can be useful in bolstering defenses or for tapping power from the surrounding masses of rock, moss and plants. Earth is the rune of vitality and the opposing element of air.
DEATH. This rune is the force of vile deeds, cowardice, destruction and darkness and it is a very potent power for deception or causing harm to others.
ICE. Ice is the source element of powerful freezing spells that can harm or slow others. Ice is the rune of willpower and the opposing element of fire.
Note: Rune symbols goes... Well, I'll just demonstrate it(pic of rune thing)◊
