Stackmon Soot Rifts: Milestones and Open Questions
The official store frames investigating Soot corruption as a core task. Steam then names two concrete Soot Rift milestones: close the first Rift and close all Rifts.
Player answer
Quick answer
Soot Rifts are confirmed objectives. Soot Purifier marks the first closed Rift, and No more Rift Points marks closing all of them.
Follow the current game’s Soot objective markers.
Prepare the team before entering a corrupted encounter.
Record a Rift location and closing condition before treating it as a reusable route.
For exact details: Use the current map and Rift cards for the total count, locations, entry requirements and rewards.

The screenshot establishes these names in that promotional scene. It does not prove encounter rules, rewards or creature types.
Soot Purifier requires closing a first Soot Rift. No more Rift Points requires closing all Soot Rifts. Neither description exposes how many exist.
How Soot connects to the larger loop
Official store copy includes investigating Soot corruption among the core tasks. Promotional imagery also places corrupted encounters inside the same card-based battle presentation.
Update if the game freezes when you return
Patch 9.0.76 lists the freeze when returning from Soot as fixed. Install that version or newer before repeating the trip. If it still freezes, record the route, last action and current version for the developer.
Use the current Soot Rift flow on patch 9.0.82
Patch 9.0.82 removes paused-time behavior inside Soot Rifts and fixes Trainer inspection after completing a Rift and returning to the route. It also makes the Soot Herb recipe always appear on Snow Route 1. Update before repeating any of those steps.
Do not plan around re-entering a closed Rift
Patch 9.0.85 fixes the ability to re-enter a Soot Rift. Update first; a route that depended on the old re-entry behavior is no longer a reliable current strategy.
If cards or money changed after a Rift
Patch 9.0.97 fixes cards duplicating inside Soot Rifts and money not returning after leaving one. Update before repeating the route; if the result still differs from the live reward screen, record the route and current build for a bug report.
Why this is not a location guide yet
A location list needs a current map, route state, unlock condition and confirmation that Rifts are not randomized or changed by progression. Those fields are absent from the public descriptions.
What to record when closing a Rift
Note the route or biome, objective text, required battle or item, post-close state, reward and build version. This helps you retrace the route if another Rift behaves differently.
