Altars
Five one-way sinks. Nothing you pour in ever comes back, but the running total crosses thresholds that never switch off again.
In short
An altar is not a station. It builds nothing, returns nothing, has no queue. It keeps a single number, the total you have poured into it, and that number is what decides your bonuses.
Pouring into an altar is final. The mana, dark mana or resources you sacrifice leave your inventory and come back in no form at all. In exchange the altar keeps a running total that never goes down. Kairos stops at 1 500 000 mana, and all five altars in the game work on that same principle.
They fall into two families. The prestige altars climb high and slowly: the Mana Altar (Kairos) over 8 tiers, the Crypt of Ikaros over 12. The job altars, three of them, are shorter with 4 tiers each, and only accept the resources of their own job.
Two doors guard every tier. The first is a place: you have to stand there to pour. The second is a level, the global one for Kairos (from 1 000 at the first tier up to 4 000 at the last) and the matching job level for a job altar, up to 3 500. The Crypt is the only one asking for no level at all: it asks that Kairos sit at its tier 8.
A bonus does not switch on at the threshold, it climbs between thresholds. Regeneration slides from 60 s to 30 s per mana as you pour, the maximum reserve climbs to +3 000, the global multiplier reaches ×2. Filling half a tier is worth roughly half its gain.
The five altars, one by one
An altar is a single number climbing toward its ceiling, and the five altars do not share a scale: one tab per altar, each with its tiers sitting where they really fall on the gauge.
The great mana sink. Every one of its tiers opens something else: regeneration, reserve, quests, then the Pyramid.
The Crypt asks for no level, which is why its cell stays empty. Its door is elsewhere: Kairos tier 8, the one that opens the Pyramid. Once you are inside, its 12 tiers depend on nothing but the dark mana poured.
Between two tiers the bonus climbs continuously. Regeneration slides from 60 s to 30 s as you pour: a tier half filled gives roughly half of it. The notch on the gauge marks the threshold, not the moment the gain appears.
A job altar counts resources one for one, whatever they are worth: 32 resources are accepted across the 3 altars, and the rarest weighs exactly as much as the most common. Pouring raw ore stays the cheapest way to climb.
