On Clanker Killer talent:
"Before rolling a combat check that targets a droid (including a droid vehicle or a vehicle piloted by a droid), the character may remove Boost up to their ranks in Clanker Killer from the pool, and add an equal number of successes or advantages (in any combination) to the results."
Do you add the success or advantages after rolling the dice pool, or before, as it isn't stated?
In the same book, Mission Critical explicitly states that the successes and advantages are added after rolling a check but before resolving, making it clear, which is leading me to suggest it is before rolling a check.
But you could argue that the results don't exist, and you can't add to them, until the dice are rolled (you'd be adding successes or advantages to the dice pool otherwise).
Clearly adding after rolling is more powerful, but given force enhanced skills do that all the time, I don't have a major issue with this as the GM. I'm leaning towards that interpretation (I also like skills that give flexibility to the player in interpreting the dice pool), but would appreciate clarity if there is any I have overlooked.
