Places to Seek Out Sol Grande In the Lost Ark, the World's Top Executive
Sol Grande may be found on Alteisen Island, or just Alteisen in-game, which is located not far from Arthetine. The island can be seen by moving the mouse to the square harboring Arthetine's ships. The port and Facility X-301 may be found in the vicinity of the square's center, while Alteisen can be found in its lower-right corner.
There are scheduled times and dates for when each Lost Ark boss appears. Starting at the same time, each timer cycles every few days. The following is a sample of the alarm schedule used by the world boss of Sol Grande.
Sol Grande is a boss that requires a certain item level in order to defeat. In order to use Sol Grande, your item level must be at least 1040. It's still possible to do damage to the boss if you're below threshold, but you'll have a harder time earning experience and reputation. If you press "P" or navigate to "Character" "Character Profile," you can view your current level with cheap Lost Ark gold.
If you're at a high enough item level to take part, you can head to the port in Arthetine and sail southeast towards the island. Sandstorm Seas surround the island, so you can try to avoid them for a while, but you'll have to cross them to go to the island. You can try your luck on the island by auto-routing there if your resilience to sandstorms is good enough.
