I've just found this item:
Couters of Second Chances (Adv I 116):
Free Action. Use this power when you miss with a melee attack. Reroll the attack, and use the second result, even if it’s lower.
And I was wondering if I could use it with the Human Racial Power "Heroic Effort":
Heroic Effort (Heroes of The Forgotten Kingdoms 264):
Trigger: You miss with an attack or fail a saving throw.
Effect: You gain a +4 racial bonus to the attack roll or the saving throw.
Let's suppose I miss an attack and I choose to reroll it with the item's daily power. If I also choose to use the Heroic Effort power, can I apply its benefit to the reroll result? Assume the first result was too low for the use of Heroic Effort making sense.
The order of the actions would be:
- Make an attack roll;
- miss first attack roll;
- use second chance;
- use heroic effort on the second roll.
