There should be some minor narrative motivation added to funnel players towards the temple/crypt. It used to be where you recruited Shadowheart, who was trying to gain entry and insisted there might be something useful inside, and that was good enough.
But now, if you rescue Shadowheart on the ship - probably the most common path - she's there on the beach with you right at the start, and the only reason to ever go there is metagame knowledge about the amulet and other loot. It would be nice to have something in-story pushing our characters that way, maybe something with Gale since he emerges from the portal nearby.
