At the convention center WiFi is only so so can you get me e wordind on favor please
Akiro's Favor:
" Once per round, if this creature makes a melee or ranged attack, you may re-roll all of the attack dice, or the effect dice, for that attack. Or, if the attack has to roll to hit (such as with a Daze condition), you may re-roll that die roll instead. Use a ready marker to keep track of this ability."
I think this is what causes the most head scratching, with an Enchantment it is possible to reveal it after one thing happens (the dice roll) and before the step that typically follows it happens (apply damage/effects) thereby interrupting (re-rolling dice) what would flow normally.
I could be wrong though.....
Yes you can reveal between the dice roll and apply damage/effects. That is usually where you use healing charm to snatch victory from the opponents grasp.
More specifically: "At the end of any of the eight steps of an attack or three steps of casting a spell."
So in order to use Akiro's Favor the enchanted creature has to make an attack or make a roll to hit. All eight of the steps are "making an attack" so anytime during this action qualifies for the first and second ability.
By the time you realize you rolled bad and wish to re-roll you will not be able to reveal this card before the dice roll step is over - The first chance to reveal would be between the dice roll step and apply damage step.
What happens here is you reveal Akiro's Favor between step 3 and step 4. That allows you to re-roll either the attack or effect dice, but before they are calculated in step 4. The only thing that is required to use Akiro's Favor is that the creature makes an attack, which it is doing.
If it said, " Once per round, if this creature
declares a melee or ranged attack........" then you could not reveal after the roll and still use the ability.
Furthermore, "if this creatures makes a melee attack or ranged attack...." applies if the creature only makes one attack that round as well. It does not need to complete the attack action to "activate" Akiro's Favor.
So the simple version is that yes you can reveal after the attack roll, but before damage and effect is applied to the target.
Lets hope that makes sense without the morning coffee.......
