 ### Effect Modes
-For some effects it makes sense to allow stacking, so a single entity could be effected multiple times at once.
-For others, each effect should only be applied once.

 ### Implementing Effects
 Effects can be implemented using simple systems. Below is an excerpt from the poison example.
