Static spell

A static spell is a type of spell that has a singular and immediate effect that does not change when cast.

Dynamic spell

These spells will require a stronger sense of concentration, since you will need to hold the concentration for a longer period of time. These types of spells will typically have either extended effects that require a continuous flow of willpower and concentration that must be directed towards the target and the effect, or effects that can be changed in the middle of the casting.

Magical exhaustion

Every time you cast a spell, you are utilizing magical energy from within you.Casting a static spell uses magical energy solely during the time it takes to cast; dynamic spells will continue to draw on your magical energy for as long as the spell is in effect.
