This is an example:
"So, lemme just lay this all out. I'm not ruling, yet.
Thomas and Harry are dueling against Madrigal and Doucheknocker (don't remember the other dude's name).
Thomas attacks Madrigal, places maneuver of Dazed for 5 Shifts. Madrigal can keep the Aspect on himself and let Thomas tag it whenever, or roll to Overcome it. If Thomas is still harassing Madrigal, Madrigal has to roll a 5 or better to overcome. If Thomas switches to Doucheknocker, then the roll to Overcome becomes 0. Either way, the Aspect stays until it's removed.
This is RAW; there's no dispute here.
Harry blasts Doucheknocker with an 8-shift Ventas Servitas! and knocks him on his ass. He puts 6 shifts into the Maneuver and 2 into Duration. Doucheknocker can roll to Overcome or not, same as Madrigal. However, if he doesn't, then Harry has to tag it within two more rounds, or it goes away. If Doucheknocker chooses to roll to Overcome, he has to beat the 6 shifts if Harry continues harassing him, or a +0 if Harry switches to Madrigal. Or, he can just wait for it to go away on its own.
Still thinking about how to rule, here, but I think the dispute is whether Harry's wind spell should have an Overcome of +0 or +6 when he switches targets, yeah?"
Essentially my group has come to impasse about how this should be ruled. I personally think after switching targets the roll becomes +0 because thematically you can't power an ongoing spell on Doucheknocker while focusing on Madrigal.
The opposition is that you've already paid for duration which mean the spell continues regardless of your target. So to remove the aspect it is +6 to beat.
My GM is currently split 55/45. in the latter's favor. I just wanted to come here for some perspective, and get some of the vets opinions.
