Thanks for the feedback...I appreciate you taking the time to share your thoughts...
With regard to the anomaly, it is true that I did not include a stat block or describe in more detail how the anomaly could be captured... I envisioned the anomaly as something difficult to deal with...so much so that defining how it could be defeated or captured would trivialize its power. Although, having no real description perhaps keeps the task too open ended. Perhaps some sort of multi-step process or series of task successes would help guide success. Thanks for bringing this up...very helpful.
