Sea of Stars has a mean cast of bosses waiting for our Solstice Warriors to kick their butt. Still, before going up in arms against Romaya, or any other boss for that matter, there’s a series of puzzles that must be solved. The Necromancer’s Lair door is closed shut, and there seems to be a skull mechanism behind opening it.
Still, traversing this area isn’t the easiest thing, especially considering there’s a key item you need to obtain before you can reach every corner of Romaya’s hideout. This guide takes you through every step of solving the Necromancer’s Lair puzzles and how to defeat Romaya in Sea of Stars.
How to Find All Three Green Skulls to Open the Door to Romaya’s Lair
To find Romaya, defeat three Revenants in the Necromancer’s Lair and open a heavy stone door with three skull-shaped holes. Each defeated Revenant will drop a skull. Once all three skulls have been collected, it’ll be time to defeat Romaya, the necromancer who’s behind Lucent’s curse.

How to Beat Boss Romaya in Sea of Stars
Romaya is, unsurprisingly, a necromancer. Her main attack involves turning the pile of bones and flesh nearby into enemies. Though it’s by no means the hardest boss fight in the game.
- Normal attack: Uses her necromancy powers to resurrect the pile of bones and a pile of flesh into Revenants and zombies.
- Charged attack: Deals party-wide damage with toxic rain
- Vulnerability: n/a
After defeating Romaya, she’ll reluctantly hand out the items you need to get back to Garl and cure him.
