Ally: These Boons typically represent an ally actively assisting the PC. This could be a hired ammo loader, a dodgy hacker, or a knightly squire from the Hellknights or Knights of Golarion.
Personal: Personal Boons represent a wide variety of special Boons available in the campaign. Uncommon playable species, typically those found outside the Starfinder Core Rulebook, are often accessed by Boons that occupy this slot. The Personal slot often requires associated Boons (such as new species options) to be permanently slotted, so that the slotted boon does not change on a scenario-by-scenario basis.
Promotional: Promotional Boons are unique in that they often represent out-of-game acquisitions that promote Starfinder or Starfinder Society and translate to in-game benefits. For a complete list of current Promotional Boons and associated requirements, see the Paizo Organized Play Perks page.
Social: These Boons often encompass agreements or alliances with in-game organizations or NPCs. The benefits of these arrangements often come in the form of a Boon granted by a Chronicle.
Starship: Starfinder Society Scenarios call out the inclusion of starship combat with the Starship Scenario tag. Starship Boons are most relevant to these Scenarios, allowing for the customization of the standard ships offered by the Starfinder Society organization. See the Starships section for more information on these Boons and customizing ships.
