Thanks for the suggestion, but as a level 11 Shadowknight, that's going to be tricky. Highpass should work, though, right? What about Qeynos?

Level shouldn't matter as long as invis sticks. You have the same percentage of risk as I do to get caught. I know nothing about the other two locations sorry.

I don't get invis until level 30.
