Game director Carrie Patel has indicated that Avowed features multiple endings influenced by key choices and smaller decisions throughout the game. The main decision involves whether to kill or spare Sapadal, which affects the ending slides. Sparing Sapadal while encouraging her darker impulses does not lead to a "vengeful" ending slide, but providing her with the Adra mech during Sargamis' quest results in a unique slide showing her peaceful use of it. Killing Sapadal aligns with the original pantheon of Eora and ends the Dreamscourge, similar to sparing her. Merging with Sapadal leads to a darker outcome where she overtakes the player's personality, also resulting in the Dreamscourge's defeat.
In the Living Lands, players can achieve different outcomes based on their choices during the council. Siding with Lödwyn and achieving the Steel Garrote ending requires specific prior actions; otherwise, players may be executed as traitors. An Aedyran colony outcome results in direct control over the Living Lands, while a "gréfram" allows for partial colonization with some governance retained. Advocating for an independent Living Lands leads to favorable outcomes for certain characters but leaves others in uncertain situations.
Optional quests can also influence the ending slides, such as Giatta's career path, Yatzli's fate depending on her choices, Marius's contentment based on quest completion, and Kai's grim fate if his quest is unfinished. Each of Kai's positive outcomes can lead to a romantic epilogue if interest is expressed.
