Soul Guise Helmet
From Starbounder - Starbound Wiki
|A helm of extraordinary dark power, it calls out to its true master|
Soul Guise Helmet is a costume hat. It can be found in chests in Glitch Dungeon Crawlers and has a rare chance of being found in chests throughout the universe.
The design was submitted by a platinum tier pre-order backer, who was granted the ability to design a hat to be included in the game.
The name and description of this hat shares some similarities to that of the Soulseeker (namely the inclusion of the word 'Soul' in each name, and the shared sentence structure of "A <item> of extraordinary dark power, ..."), implying that both of these items maybe have been submitted by the same backer.
