Hello,
In some games we made, i think we made some mystakes about timing and the steps of modify dice. So i ask for you to be quite sure.
1 exemple: Wolverine made a Adamantium Slash and roll a crit and a wild so at step 8 of the timing he re-rolled the crit and if his opponement had crit(s) in his roll he can re-rolled also. Then at the step 9 Wolverine can modify a dice in the opponement pool because he had a wild/pierce in his pool. But Pierce can never modify the initial throw and cancel a crit.
So if i'm right i presume it works like this for characters like Black Cat or Angela: they can't prevent modifying dices in the step 8 but only on step 9.
Sorry if there's only a topic. And sorry too for language: i'm french !!
