In response to dirkin's review:

1. Awareness alone can now break an illusion. What I'm worried about with this mechanic, however, is the metagame making it useless in a combat setting. The RPer knows it's an illusion, so his/her characters instantly become aware as well. I don't think it will be a major issue, but I feel obliged to at least bring some attention to it.

1 and a Half: I stuck in a footnote saying that more people in an illusion equals less stability in the illusion, making it easier for everyone involved to escape. If one becomes aware, he/she can bail everyone else out. Someone on the outside can also interrupt an illusion. Doing anything like a time limit would just prove to be confusing, since the perception of time can also be messed with, meaning that second could feel like hours, etc.

2. Astaroth is an A-class mage as of right now, but he could be promoted to S-class once the plot deems in necessary/acceptable. I have no issues with this setup.

3. Phoenix Wing's master helping Astaroth further control his magic sounds like a grand idea. I'm all for it.
