The Costa Valor has a total of five crossbow targets for the Luminary to shoot. They’re all fairly easy to find, but you’re going to have to go well out of your way to do so. In fact, one of them is in the water at the very edge of the map — a location that most people wouldn’t bother going to under normal circumstances.
Here are their locations:
1. Hanging from a tree directly to the north of the area’s sole campsite.
2. On the southern part of the hill separating the entrances to Mount Pang Lai and The Manglegrove.
3. At the edge of the map off the northern-most coast in the area.
4. Hanging from a tree on a cliff located directly south of the small channel connecting to the two coastal areas of the map.
5. Hanging from a tree directly to the north of Puerto Valor.
Upon shooting all five targets, head back to the area’s sole campsite to receive four seeds of sorcery.
