Companions, or legendary keepsakes, are items that you can equip that will give you a summon ability during your runs. To get them, you will need to farm Nectar which you can then give to various NPCs to increase your relationship level with them. After giving them six Nectars, each NPC will reward you with a companion.
How to equip Companions
To equip your companion, you will need to visit the display case in the courtyard at the start of run, and you will not be able to change it during a run.
It is possible to upgrade your companions, getting more uses from them during a run, by using Ambrosia.
