The Dead Suns Adventure Path is sanctioned for use in the Starfinder Society Roleplaying Guild. Download the Dead Suns Adventure Path rules and Chronicle sheets — (427 kb zip/PDF)

Starfinder Adventure Path #1: Incident at Absalom Station

Equipment: Noqual as listed in the sidebar on page 26 is permitted, but only for ammunition and melee weapons; all items on pages 50-53 are permitted, except Ungarato.

Starfinder Adventure Path #2: Temple of the Twelve

Equipment: All equipment in this book is legal for play except the Ring of Fangs.

Class Options: The devastator connection is not legal for play.

Starfinder Adventure Path #3: Splintered Worlds

Equipment: All equipment in this book is legal for play except the grave wind necrograft.

Starfinder Adventure Path #4: The Ruined Clouds

Equipment: All equipment in this book is legal for play. Eohi boots must be worn for 24 hours before the wearer can benefit from their ability. A wearer cannot combine the full attack action associated with the eohi boots with any other class feature that might alter full attacks (such as flashing strikes or soldier’s onslaught.) The suggested alternate versions of the queller are not legal for play.

Starfinder Adventure Path #5: The Thirteenth Gate

Equipment: All equipment in this book is legal for play except for the Holdall Raiment. Relics do not sell for full resale value, but can be sold for 50% of their value instead of 10%. Relics do not come with ammunition (which must be purchased separately). Disruption equipment has serious downsides when used in environments that are not on the Material Plane (including the Drift) which are repeated here for GM reference:

Disruption pistols and rifles expend twice the usage and have half the range when used on any plane other than the Material Plane. If used in the Drift, they deal damage to the user rather than the target on any attack roll of a natural 1. Disruption grenades work in a way similar to the rifles and pistols. Temporal disruption grenades, on the other hand, slow down the rate of subatomic movement, halting those affected by it for a short period of time but not otherwise damaging those within the blast. The radius of a disruption grenade’s explosion is reduced to 10 feet if it used on any plane other than the Material Plane. If used in the Drift, those caught in the blast radius can roll their saving throws twice and take the better result when attempting to halve the amount of damage taken or negate any secondary effects.

Starfinder Adventure Path #6: Empire of Bones

No player-facing options in this book are sanctioned for use without a boon.
