Keepsakes

"For those who truly know their friends."

Keepsakes are items that can be equipped to obtain some sort of benefit during an escape attempt. They are acquired by giving Nectar to various characters. Hades is unique as in his keepsake is only available after finishing the main storyline. If you give him any Nectar before doing so you will not receive the keepsake.

A keepsake can be equipped in the display case in the courtyard before a run. Once a keepsake is equipped, it cannot be removed, only exchanged for a different one. Keepsakes may be changed mid-run after defeating the final boss of each area, in the room after the boss. Closing the keepsake display after changing keepsakes will lock the display from being accessed again until the next post-boss room. If you switch out of a keepsake mid-run, you cannot switch back to it for the rest of the run.

Keepsakes automatically get permanently upgraded when enough encounters are cleared while the keepsake is equipped. A cumulative total of 25 encounters cleared is required for upgrading a keepsake to rank 2 and 50 additional encounters are needed for rank 3.

Olympian keepsakes (e.g. Aphrodite's Eternal Rose, or Poseidon's Conch Shell) do not guarantee that the boon will appear in the first room - only that the next time a boon is generated, it will be from that god. They also work only once per run, unequipping and equipping them between biomes does not reset the effect. A Hermes boon or a Trial of the Gods can appear before a regular boon, but it won't consume the keepsake's effect. Hermes's own keepsake, the Lambent Plume, does not call upon him like the other Olympian keepsakes.

Some of characters give you Companions (also known as Legendary Keepsakes). They are acquired by giving Ambrosia to that character after completing a quest for them.
