Relenting Question

[Virtus]

Say you want to relent an attack. Do you declare relenting before or after flipping for attack? I assumed you declare relent before seeing any cards, but was ruled in a game that you can in fact declare an attack, flip the card(s) for attack, and then choose to relent or not before defender flips.

[Adran]

Whenever two friendly models are engaged in an Opposed Duel, the
defending friendly model may choose to lose the duel. Before any cards are
flipped, the Defending model may choose to relent. When this happens, the
Attacker flips as normal, and the Defender flips no cards, it is instead assumed
that the Defender tied the Attacker’s final duel total, without any suits. page 27
