Does Skyfall of Areion apply to other equipment items on a unit? In this example I have Skyfall and Trinity Force attached to Lucain that just conquered so do I get two points?

Yes, you do.

According to the official Riftbound FAQs regarding the interaction between Skyfall of Areion and Trinity Force:

• Equipment abilities are appended to the unit's text: When you attach equipment to a unit, that equipment's text effectively becomes part of the unit's rules text. Because of this, equipment can reference the abilities granted by other attached equipment (FAQ #225, FAQ #2017).
• Skyfall of Areion's effect: This card makes the unit's "hold" effects also count as "conquer" effects, and vice versa.
• Interaction result: Because Trinity Force's "When I hold, score 1 point" effect is appended to Lucian, and Skyfall makes that effect also count as a conquer effect, Lucian's conquer now triggers Trinity Force's ability.

Regarding the points:

• You score 1 point from the standard game action of conquering the battlefield.
• You score 1 additional point from the Trinity Force triggered ability (which is treated as a conquer effect due to Skyfall).
• Total: You score 2 points total when conquering with Lucian equipped with both Trinity Force and Skyfall of Areion (FAQ #6941).
