People across the land of Tellus are suffering in the Age of Calamity and still seek help from the gods they have always prayed to. But with the relics missing, the gods can no longer answer those prayers. In the Realm of Liminalis, the gods beseech the Twiceborn to help those wretched souls on Tellus where they cannot. When those prayers are fulfilled, the Faith of those who pleaded for help is rewarded to those who aided them.
In game, Faith is a resource obtained by answering the prayers of the people of Tellus. You can obtain prayers to be answered at the Menhir of Orisons. Faith is portrayed by a paper phys rep, which you can spend to do a multitude of different actions. Every character that participates in fulfilling a prayer will receive a Faith reward. Faith can be spent on a number of actions relating to Downtime activities.
Spend Faith to bolster a god's realm
By spending 15 Faith, you can permanently upgrade a god's realm. By doing so, you can increase the resources that characters can obtain when visiting that god realm during downtime. As an example, if your downtime action is to visit the realm of Alleyar to gather Quantum Crystals, you would normally get 5 crystals. If this realm was bolstered by Faith, you and anyone else that would visit that realm would get 10 crystals during that downtime. The more times that a gods realm is permanently upgraded, the fewer additional resources are going to be gained by each level (diminishing returns).
Spend Faith to enhance an Enclave's Stability
By spending 10 Faith, you can upgrade the stability of an Enclave to full by boosting its Great Temple's protective aura. Mechanically this just reduces the likelihood of a Bloodless attack or a corruption of the populace and makes it much less likely to fall.
Spend Faith to give a Faction military unit another action
By spending 5 Faith, you can give a specific Faction military unit an additional action in next round of downtime.
Spend Faith to create new Faction-specific military units
By spending 20 Faith, you can create a new Faction specific military unit that can take actions in the next round of downtime. This is a permanent addition to the Faction forces on the War Table. You must determine what the military unit specializes in and where it starts.
Spend Faith to create an Realmway Ticket
By spending 5 Faith, you can create a Realmway Ticket. To learn more about Realmway Tickets, please see the Downtime Actions subpage under Downtime.
This list of options may be added to in future events, and may depend on what actions are taken in the story that the characters are telling.
