"Crota was... predictable," said Sigma through his Ghost, "he moves and attacks in specific patterns. This Taken facsimile does not have all of the power of the original, but it likely has powers that are yet unknown to us. Anything done from here on out should be done with the utmost caution," he pauses, taking a moment to dodge away as the shade of Crota swings its blade his way. "Try taking down its shields. That should bring it to its knees. However, a sword of Hive origin will be needed to damage it, if my memory is correct." Despite his familiarity with Crota and his behavior, he had a foreboding feeling that this creature would not behave as expected. However, they should continue like this until further action can be taken.
