How This EV Score Works
This page scores visible costs, visible rewards, and the run state you enter here. When a line depends on hidden rolls or inventory details, the page marks it with lower confidence instead of faking precision.
If the event clearly spends HP, Max HP, gold, removals, transforms, or upgrades, those parts anchor the score first.
Context wins
The same event changes by run state
A removal line is worth more with real junk left. A gold sink is worse when the wallet is thin. A potion trade is dead if you are not carrying one.
Honest limits
Hidden rolls get lower confidence, not fake precision
When an event opens a random case, delayed payout, or seed-based trade, the score stays useful but the page tells you where the uncertainty starts.
Calculator Editorial
What This Event EV Tool Is Actually Doing
This page is not a fake win-rate simulator. It scores the visible costs, visible rewards, and the run state you enter, then discounts lines that depend on hidden rolls or inventory assumptions. That makes it useful because it is explicit about where certainty stops.

What It Solves
It ranks the choices you can actually take right now
Event pages become useless when every option is treated as equally abstract. In reality, a removal is worth more when junk is still in the deck, and a relic trade is dead if you are not carrying a tradable relic.
This tool exists to collapse that context into a readable order: which line is ahead, what is driving that lead, and whether the line is genuinely available with your current run state.
Use it when you want a fast read on event branches without manually pricing every cost and payoff.
Do not use it as a promise that one line wins the whole run tree. It is a decision aid for the current prompt.
Input Meanings
The run profile fields are not decorative
Act, current HP, max HP, gold, removable cards, upgrade targets, transform targets, potion slots, carried potions, tradable relics, and enchant targets all feed directly into the scoring weights.
Focus changes the weighting profile on purpose. Survival makes HP losses hurt more, Greed prices gold and long-tail rewards higher, and Balanced keeps the weights near the middle.
Removal, upgrade, and transform value is capped by the target counts you enter.
Potion and relic trade lines flip to unavailable when you do not enter enough carried potions or tradable relics.
If your input profile is wrong, the recommendation is noise. The page tells you that up front.
Rule Basis
Visible value first, confidence penalty second
The scoring starts from concrete effects: HP change, max HP change, gold, removal, upgrades, transforms, relic gain, potion gain, curses, enchantments, and explicit fight-risk costs. Each piece is valued against the run profile you entered.
After the breakdown is built, the tool subtracts a confidence penalty from lines that rely on hidden rolls or delayed payouts. High confidence loses nothing, medium confidence loses 4 points, and low confidence loses 8.
Unavailable lines get pushed down because the current inputs cannot pay their real cost.
Delayed relic payouts, relic trades, potion trades, and random case branches are deliberately marked with lower confidence instead of fake precision.
The breakdown rows are the real score pieces, not decorative labels.
When It Drifts
Seed dependence and hidden inventories still matter
Some event lines depend on relic offer pools, potion conversion pools, divination rolls, or future fights that the prompt does not expose. Those cases are still worth scoring, but they cannot be treated as exact.
Fight-risk lines are also compressed into a penalty rather than a full combat simulation. That is the correct compromise for an event tool: fast enough to use, honest enough not to lie.
If an event says the confidence is low, read the top option as a lean, not a verdict.
If your deck state changes after one reward branch, re-score the next page instead of carrying the old answer forward by faith.
Worked Example
Default Act 2 profile on The Sunken Statue
With the default profile on this page, The Sunken Statue opening choice ranks Grab the Sword first. That line gets a raw relic value of 38 for Sword of Stone, then loses 4 because the page marks it as medium confidence, for a displayed score of +34.
Dive into the Water looks tempting until the math is explicit. The same profile prices the 7 HP loss at -45 and the 111 gold gain at only +27, then subtracts the medium-confidence penalty to land at -22 overall.
Grab the Sword: +38 relic value, -4 medium-confidence penalty, final score +34.
Dive into the Water: -45 HP cost, +27 economy gain, -4 medium-confidence penalty, final score -22.
That is why the recommendation leads with the relic line instead of the gold line.

DisclaimerExpected-value tool, not a promise that every hidden branch is solved.
If an event hides a roll, future reward pool, or unexposed rule branch, the page should stay conservative instead of pretending to know the unknowable.
Gold, removals, upgrades, transforms, potion slots, and tradable relics move event value fast, so the calculator reads them directly from your current run.

Each line below shows its weighted score, the score pieces, and a confidence label when the result depends on hidden rolls, delayed payouts, or inventory details.
No. It is a weighted EV page built from visible costs, visible rewards, and your current run profile. That keeps it fast and useful without pretending the full run tree is solved.
Why do some lines show medium or low confidence?
Some events rely on delayed payouts, dynamic trade offers, random cases, or inventory checks you cannot read from the prompt alone. Those lines still get scored, but the page marks the confidence honestly.
What should I change first when a recommendation looks wrong?
Usually the answer is the input profile. Gold, removable cards, upgrade targets, potion count, and tradable relic count are the biggest swing points on event pages.
