Steps:
We were fighting Magiteck Colossus Rubricatus as normal, at 50% of its health we killed the adds and its physical sheild dropped visibly but it continued to take only 1 damage per hit. After a while of beating on it with the shield no vanishing and no other targets we attempted to use Return to reset the fight. It again displayed the same behavior at 50% health. At which point we gave up and exited. I have cleared this dungeon many times and have never seen this behavior before.
