Do I have to declare an item before rolling the attack modifier?

Question

Accepted Answer

Only items that grant Advantage (or otherwise affect the draw) must be declared before you draw the attack modifier. The designer says effects like +1 Attack, added conditions or treating a rolled result as a different result can be decided after you see the roll, though he hedged on this. Note the rulebook says attack effects are chosen before the modifier is rolled, and many players play it that stricter way. Movement items can be decided just before you move.
