Thanks for your input, marbleman. I agree that the mystic eyes should be bust because they don't kill the clones in one go, but they get spotted in between each shot. However, the clones spawn in hunt mode, so they are already alerted upon appearing. But yes, I can go along with that. They do become AIs though, modified fire elementals in the way they operate, so they shouldn't be directly compared to mines or arrows. I used that argument to compare them to turning on the bots nearby; they are obviously AI fighting on your side.
A script is something that is triggered outside the player's control as a part of the story progression in the mission. Sometimes you can choose to trigger it, and other times it is forced. Such scripts are linked to something Garrett does, but not always a direct result of it. The gem of oldorf is not released by using a switch but by reading a scroll. The spiders being released I was unsure of, but since all I did was open the cage and then suddenly their patrol route getting altered, I figured this was a part of a script change. But that one might be more borderline. Pushing the button for the bots has only one purpose, namely to turn on the power source that energizes them and turns them on. There is no script linked to this, it is a direct and intended result of Garrett's involvement.
Thanks for the other reports, Galaer.
