If you hold a battlefield, retreat from it, and then move back to conquer it again in the same turn, do conquer effects (like Sett getting a buff) trigger even though you don't get a point?

Ruling: No, conquer effects do not trigger. Conquer is a subtype of scoring, so if you cannot score (which you cannot do twice on the same battlefield in one turn), you cannot conquer.

Sequence:

• You hold the battlefield
• You retreat, leaving it empty
• You move back into the battlefield
• A showdown occurs on re-entry
• The move completes but no scoring or conquer effects occur

Nuances:

• You can only score in each battlefield once per turn
• Even at 7 points where "scoring" draws a card instead, you still need that scoring action to occur for conquer effects to trigger
