When Haradrim Elite is revealed from encounter deck, you must do the forced (immediate attack).
In faq1.5 the new rule is:
(1.26) Enemy attacks outside of the combat phase If an enemy attacks outside of the combat phase, it is still dealt a shadow card at the beginning of the attack. Then follow the 4 steps under Phase 6 "Combat" in the rules. Any shadow cards dealt to the attacking enemy are discarded after the attack resolves.
So you can play actions inside the 4 steps of combat phase.
So, for example, yesterday i was playing with Bard, he was ready when in quest phase Haradrim Elite was revealed. After it dealt a shadow card, i played
Hands Upon the Bow
, and i killed Elite before it attacked. Is it correct?
