Side Effect
From D20advanced
| SIDE EFFECT | -1/-2 Modifier |
|---|
Failing to successfully use an FX with this flaw causes some problematic side effect. Failure includes missing an attack roll, or failing to overcome the target's resistance. If the side effect always occurs when you use the FX, it is a –2 modifier. The exact nature of the side effect is for you and the Gamemaster to determine.
As a general guideline, it should be an FX about the same in value as the FX with this flaw, not including the cost reduction for the flaw. So an FX with a cost of 20 points should have a 20-point side effect. Typical side effects include Damage, Drain, and Inflict (Condition), or the same FX as the FX (it essentially rebounds and affects you). The Side Effect does not require an attack roll and only affects you, although the GM may permit some Side Effects with the Area modifier on a case-by-case basis.
Some “side effects” of FX may actually be Temporary Disabilities.
