Darkness Falls: gods and prayer

A Darkness Falls player favors one of three gods and prays to it once a day for its blessing. A blessing only adds to what the player has; choosing another god takes nothing back.

God	Domain	Blessing
Seraphine	mercy	Closes the player's wounds to full health and fills their healing potion.
Orrin	fortune	The next ten kills pay a quarter more gold, on top of any held from a Potion of Fortune.
Kharos	war	The next ten kills give half again the experience, on top of any held from an Experience Elixir.

How a player uses it

• "favor Seraphine", or "favor mercy": the god is heard by name or domain, and the player hears "You favor Seraphine, god of mercy. Say pray once a day for Seraphine's blessing." with a pray option. "choose a god" or a favor with no god named lists the three: "Say favor Seraphine for mercy, Orrin for fortune, or Kharos for war."
• "pray": the favored god answers once a calendar day. A second prayer that day hears "You have prayed today. Seraphine hears you again tomorrow." A player who favors no god hears the choices.

Where it lives

• The gods and their domains: DarknessFallsGod. The blessings and both commands: (favorGod, pray).
• The favored god and the day of the last prayer are account counts, DF_FAVORED_GOD and DF_LAST_PRAYER_DAY, so they hold across characters and are not part of any cached character.
• Fortune and war ride the per-kill counters the gold and experience consumables already use (premiumGoldBonusCombatsRemaining, premiumXpBonusCombatsRemaining), so a blessing is paid by the same kill code.
• The phrases and dispatch rows: the feature's process_action_handlers-gods-and-prayer.sql.
