The situation: a very messy firefight. The enemy Anvil commander is trying his darnedest to find the rebels and get a lock on them, but the rebel kerrn commander’s been jarred by some suppressive fire- so the other PC, an insurrectionist has taken over.
So it’s Advance vs. Observe, as the rebels try to storm the food depot (a Position 3 location.)
My dude has 4D Observation, and gets 2 successes. He also wears Anvil Armor that gives him +1 obstacle to all his Observation rolls.
Tavis does not have command. He rolls his Beginner’s Luck Will of 5, and gets 3 successes.
So, I think this is a tie- Tavis needs to get twice as many successes as me, which would be 4, but I have +1 obstacle, so that’s 3 instead. So I don’t exceed what I needed to get to Observe him. (Unless the +1 obstacle in a versus test translates to -1 success, which would give Tavis and obstacle of 2. He’d still fail, because it’s a Position 3 place.)
So, that’s curious, because however you calculate it, we both pretty much fail.
But I want to know what to give Tavis for his advancement. Is this a Routine test (he only needed 2 successes- my 2, minus 1, times 2, or if he needed 3, my 2 times 2, and then minus 1), a Difficult test (he needed 4- my 2, times 2, and my +1 obstacle doesn’t factor into his calculation), or a Challenging test (if the +3 Position of the position counts as an obstacle increase- he was trying to beat me by three, but the text of Advance does not specify that this is actually an increase in the obstacle.)
