EFFECT: Blades/Claws/Fangs. When this character uses it, you may instead use one of the dice in the attack roll as your d6 result.
XoS061 Saturnyne has this damage power:
OMNIVERSAL MAJESTRIX Leadership, Perplex. // Once per turn, you may reroll a die rolled by a character within range (including one die of an attack roll).
Two questions (that are related)
1. When using Grasscutter, do you still have to roll before choosing to use one of the dice in the attack roll for Blades?
(Depending on the above answer) Is Grasscutter's additional effect a die replacement? Meaning, could she reroll the Blades roll before a character choose to use one of the dice from the attack roll for their result?
