A-Grade Page Scope
Read The Blessing Lane Before You Read The Relic
The page exists to narrow Ancient choices by act timing, lane structure, and shell fit instead of flattening them into one fake tier list.
When It Helps
Best when the blessing question is still route-facing
Use it when act, area, character, focus, and solo-versus-co-op status are the variables that actually decide whether a blessing line is live.
Where It Lies
Fit score is not a universal ranking
A high score only means the visible shell and timing line up. It does not mean the blessing is always premium once future shops, removals, or off-page pivots enter the run.
Input Boundary
The page only scores visible run context
Ancient lane, character, focus, and mode are modeled. Hidden future conversions, unknown relic drops, and lines that depend on information the page cannot see are not.
How It Works
How the Ancient Blessing Evaluator Scores Blessing Fit
This evaluator filters the available Ancient blessings by your current act, area, character, and focus, then assigns a fit score based on how well each blessing's timing and lane structure aligns with the shell you are piloting. It is a narrowing tool, not a universal tier list.

How to Use It
Set your run context, then read the fit scores in order
Start by setting the Act, area, character, focus, and whether you are playing solo or co-op. The evaluator filters the blessing pool to Ancients that can appear on your route and sorts the visible blessings by how well their timing and lane structure align with the context you entered.
The fit score is a route heuristic, not a universal ranking. A blessing that scores well here is one whose timing and lane bonuses land cleanly in the current run state. A blessing that scores poorly is one whose value requires conditions that your current context does not support.
Change the Focus filter to shift scoring weight between combat efficiency, economy, and long-run payoff.
In co-op mode, team-oriented blessings receive higher weight because shared-turn value is more accessible with multiple seats.
The Reading Panel at the bottom of the page explains the specific scoring factors for the current filter state.
What the Fit Score Measures
Act timing, lane structure, character compatibility, and mode fit
The fit score combines four factors: whether the blessing's power peak lands in the current Act, whether the blessing lane is compatible with the character's primary game plan, whether the focus filter aligns with what the blessing provides, and whether the solo or co-op mode changes the blessing's relative value.
Blessings with high Act-timing scores are those whose payoff arrives before the Act ends. Blessings with low timing scores offer value that only fully materializes later in the run, which may still be correct depending on your planning horizon.
What It Cannot Score
Future conversions, off-page relic drops, and multi-Ancient combos
The evaluator scores each blessing independently against the visible run context. It does not know whether you have already taken a complementary blessing, whether a future event offers a conversion, or whether a relic outside the page changes the relative blessing value.
If your run has a specific multi-Ancient plan in mind, treat the individual fit scores as a sanity check on single-blessing timing rather than as a verdict on the full plan.

DisclaimerTool output is only as honest as the current inputs and published assumptions.
Bad inputs, hidden fight modifiers, or unsupported edge cases still produce bad conclusions. The tool does not guess those for you.
Late routes usually give less time to convert slow value.
Act 3Khimera King
Tanx
Tanx is blunt: weaponize the deck, upgrade the attack shell, and end fights faster.
Glory
If the deck already attacks well, Tanx usually offers the cleanest Act 3 snowball. If the deck wins through powers or passive damage, be more selective.
Tanx shuffles a weapon pool and shows any three of them.
Tri-Boomerang only joins the pool when at least three cards can take Instinct.
There are no guaranteed lanes, just three shuffled weapons.
Weapon Pool
Three offers are drawn from this pool after a shuffle.
When you encounter the Merchant, immediately obtain EVERYTHING he sells.
Gold economy
Late routes usually give less time to convert slow value.
How to Read the Evaluator
Read the lane before the relic
The lane structure matters. Some Ancients guarantee one pick from each pool, while others hide the real value behind weighted rolls or mode checks.
Score is about fit, not fantasy
The score is deliberately biased toward what your route can cash in now. A clean premium line in Act 1 can become dead cardboard if the deck already solved that problem.
Respect visible taxes
Max HP cuts, co-op locks, and deck-state requirements are where players throw runs. If a blessing asks for a cost, assume the cost matters.
