Update 17: known effects, potions and discovery
Night Eye, Silence, Slow, Jump, Dispel and Drain Fatigue were added to alchemy. Existing effects were redistributed. Selecting ingredients no longer reveals that they share an effect while that effect is unknown; a missing interface hint is not proof that the combination has no shared effect.
Some restorative effects were moved later in the reveal order when eating ingredients, without changing their relative distribution. The alphabetical list and discovered-effect filter from Update 16 remain useful interface context, but neither supplies a verified current recipe table.
The potion system now has four quality levels, distributed through chests and vendors. Restorative potions work over time rather than instantly. Exact labels, durations, magnitudes and quality multipliers still require recorded current-build observations.
Four levels are not four verified multipliers
The official announcement says quality levels are distributed through chests and vendors. It does not list the exact displayed names or prove that value, magnitude and duration scale by one common multiplier.
Record the label you actually see together with effect, source and tested build. Use a neutral ordinal only for your own comparison, not as a claimed official quality name. The Potion Quality Log keeps observations as observations and does not estimate missing effects.
Restoration happens over time
Do not assume the entire listed restorative benefit arrives immediately when using a potion. The patch gives the direction of the change, but not a universal tick interval, stacking rule, cancellation rule or exact duration.
For an observation, note the initial resource, visible effect wording and subsequent changes. Avoid treating a delayed increase as proof of failure before checking the effect text and the current build. This is a testing suggestion, not a verified timing formula.
Merchant excess inventory: every three in-game days
Update 17 states that merchants clear excess inventory every three in-game days to avoid inventory problems. This is the current excess-stock cleanup statement; the Update 14 daily crafted-potion removal note is historical context, not the current interval to use for this behavior.
Do not extend that interval into a claim that all vendor stock, gold or prices reset on the same schedule. Update 16 also fixed merchants paying more gold than they held for crafted items. Record the merchant, available gold and actual offer rather than assuming a profitable repeatable loop.
Next steps and evidence
This guide summarizes the official announcement, not a completed in-game test. Use the source cards to inspect the developer’s wording and keep your own tested build attached to any conflicting observation.
