How does Enemy of My Enemy work?

Yea, but the next time my group gets together, I will offer my new position on the spell as:

First, you perceive only the target with compelling reasoning he is a serious threat that needs to be immediately eliminated. In order to achieve either control or illusion sides, your perception of the actual target is masked, thus you can’t gauge it for specific resistances and weaknesses, therefore you will use best means currently available, even if the end result is wasting abilities.

As such if the target becomes under the effect of a spell, you can’t see any effects because your view of the actual target is clouded either visibly or mentally.

Sad part that although there is a risk of the high damage potential can be lost because the target is under significant strain or recovery, as a GM you know that when a player uses an action other than casting a spell or using a weapon trick or technique, you it is a safe bet they would recover or have reduced strain in that time. Although generally, I have found martial characters far more dangerous from being easier to predict the most effective attack. Casters are a bigger issue because of gauging how far above passive casting, risking the CTN roll, would such caster go for die bumps or other nasty effects.

We will need an answer on casters in regards to CTN boundaries on spells. Strain is only one factor, and there are circumstances we will all agree to risk a CTN roll for a more effective spell.
