What changed recently
Ver. 1.1.1 fixed perk persistence between floors, Ver. 1.1.2 fixed shrine progress saving/loading, and September 18 rebalanced prayers and introduced a shrine-based Dungeon+ unlock.
Read the dated update timelineRead the current stake first
An altar decision depends on what is already in the bag, remaining health and resources, and route familiarity. The same uncertain effect is easier to justify early in a low-value learning run than after finding a milestone item.
If the displayed text does not make the tradeoff clear, preserve the haul. An unknown state should not be treated as a free upgrade simply because other altar outcomes can be powerful.
Separate named states from exact mechanics
Midas, size changes, manic, and depressed states are official examples, but their exact coefficients, durations, and interaction rules are not supplied in the store description. Describe only what the current interface or controlled observation supports.
Demo Update 2.0.1 documented prayer and Midas text corrections; September 18 later rebalanced prayers again. Recheck current wording and visible effects before relying on an older screenshot. Ver. 1.1.1's perk-transition fix and Ver. 1.1.2's shrine save fix describe persistence, not exact effect strength.
Recalculate the exit rule afterward
A beneficial state can encourage overconfidence, while a downside can make the planned route unacceptable. Immediately revisit health tolerance, combat pattern, mobility, and haul threshold after accepting any effect.
Record the altar, visible text, biome and build when safe. The Dungeon+ announcement separately tells players to find a shrine after a censored encounter; it does not reveal a boss name, location or interaction sequence. Keep that unlock question separate from the risk of an ordinary prayer during a run.
Outdated advice to avoid
Demo prayer text and old effect values are historical. The Dungeon+ unlock shrine is a progression feature; its announcement is not a complete table of altar effects, durations or probabilities.

What altar effects are officially named?
Official material names Midas, size-changing, manic, and depressed states as examples of radical build changes.
Are altar percentages known?
The September 18 update confirms prayer rebalancing but publishes no complete current table of effect strength, odds or duration. Read the current effect and keep measured observations separate.
How was this guide verified?
