[Dezark]

When afflicted with Confusion, your allies attacks and tiles affect you rather than just your attacks affecting them.

To repeat this
Have Ranger use Thunder Cross (or w/e the one that makes the circle is called) while in range
Get hit by hot lips mind melter and get confused
Ranger skill pops next round, you take damage.

It seems to make the game act as if your on the enemy team rather, so that they can attack you as a whole rather than your attacks affecting them in turn.
