I cannot allow that, [@Lucius Cypher]. If you roll with advantage, you have used something to gain the advantage. Scouting it beforehand like that is abusing the system, I find. In case of disadvantage, I can factor that in myself or ask you to provide the second roll. Were it not for the fact that you can pop advantage whenever you want, I might be willing to look past this, but since you have the at-will ability, it cannot stand. I hope you understand.
