The Almanax lets players benefit from daily quests and bonuses. Every day of the year, players can go to the Temple of Scriptures to complete an Offering to (Name) quest which gives kamas, XP, Almokens, and a Calendar Page. 365 pages will reward the Year of the Dragon achievement, which gives a Dolmanax.
Additionally, the Almanax will reward daily bonuses on XP, drops, gathering, crafting, etc. based upon the offering of the day.
A full list of all offerings, bonuses, and kama rewards is at Almanax/Offerings.
