Quote from: Skarg;848819I see. That's cool, and makes sense for a chaotic failure result. It also avoids people trying to game failures by knowing exactly how they work.

For the doubling effects though, I was wondering about successes. Does it have to be used to make an escape? Can you instruct your double to attack the enemy, so essentially this gets you a disposable suicide copy of yourself? Can your double cast spells?

Quote from: ZWEIHÄNDER;848824It specifically says "double the duration", so no. You'd only extend the duration by x2.

Quote from: Skarg;849028Ok, but that's not what I meant by doubling. I meant, it says you can tell your double to do something, and run. What if you also know other spells, including something you could cast without directly affecting others so you won't lose the invisibility. Can you tell your double to cast obvious spells, or stay and fight, while you, instead of running away, stick around and cast spells that won't get you discovered? Or even, say you know this spell and fireball - can you cast this spell, tell the double to cast fireball, and then not care about your invisibility and cast fireball yourself. i.e. Can you use it not to run away, but to create a friendly doppleganger and so double your own fighting power?
