-### Spells
+When a spell is cast, use the combat system to determine the outcome.
+
+### Spell structure
+
+There is no "spell list" like there might be in other settings or other systems. Instead the creativity is left to the players and the game runner, here is how a spell is determined. A spell can be written down for conviniance, but certainly does not need to be since it can be redetermined later on. 
+
+#### Spell Casting Level
+
+The casting level of a spell is determined by adding all the affinity levels of a spell together. 
+
+#### Spell Difficulty Level
+
+The difficulty level of a spell is determined by multiplying all affinity levels of a spell together, if an affinity level is 1, use 2 instead.
+
+#### Spell Affinity(s)
+
+A spell may have one or more Affinitie levels (example: heat 4, technology 2), provided they do not conflict with an opposing Affinity. A spell cannot use heat and cold for example, this means a spell can have up to 5 Affinitys, one for each spectrum, this however is not required. 
+
+#### Spell Form
+
+The spells form determines its use. There are 3 forms, they will be explained below. A spell may only have one form.
+
+##### Bolt
+
+This form is the most traditional, the spell is thrown by the creature at another creature.
+
+##### Infuse
+
+This form is used to by touch, the spell is infused into a creature by another creature by contact.
+
+##### Meditative
+
+This form is not showy, the spell is used within the creature casting it.
+
+### Example spell
