In three recent fights with the colored knights that precede Marcus in zone four, when I used a magic attack and criited, the depleted soulstealers and acid flasks hurt my enemy instead of me. The first time was with enchanted arms, the second with mirror rorrim copying enchanted arms, the third with healing light.
Not that i mind the wins, but this is obviously a bug.
EDIT: And just now a fourth time with spirit ward. Now that i think about it, I believe the enemy has had both at least one breastplate of warding and at least one rune of reflection left each time, not sure though. Also, this is on normal difficulty as a sentinel, in case either factor may be relavent.
EDIT, AGAIN: And a fifth time with transferance where i can confirm the presence of both talismans.
EDIT THE THIRD: And a sixth time with healing light where, again, he had both talisman types
