Vampire's Coffin
The right first purchase depends on why a run is failing. Recovery and Reroll fix unstable runs; Greed pays back faster when you already clear stages consistently.
Practical decision
Recovery level 1 costs 500 coins and restores health after encounters. Buy it first when otherwise promising runs collapse through chip damage. Do not immediately max later Recovery ranks; the first level fixes the mechanic, while later coins may solve more problems through Reroll or damage.
Practical decision
Reroll level 1 costs 250 coins. It is the cheaper first fix when survival is acceptable but reward screens repeatedly miss the needed Base Card, Item Card, or curve piece. One reroll can rescue an evolution plan more often than a small universal stat increase.
Practical decision
An economy-first guide recommends pushing Greed to roughly rank 2 or 3 because each rank compounds future coin income. That route is sensible only when the current build already clears early stages. If runs die before banking meaningful gold, buy the survival fix first and return to Greed later.
Practical decision
For unstable accounts: Recovery 1 -> Reroll 1 -> Duration 1 or 2 -> Might 1 -> Luck 1. Duration keeps important Crawler buffs active longer, while Might and Luck add broad value after the run is no longer failing for structural reasons. Treat this as a diagnostic route, not a permanent universal ranking.
Practical decision
The shop supports refunds, so early purchases are not a permanent trap. When a new dungeon changes the problem from chip damage to boss damage, move coins accordingly. A useful upgrade plan follows the current failure screen instead of copying one tier list forever.
Practical decision
Might does not make a missing recipe partner appear, Luck does not repair a broken mana staircase, and more maximum health does not replace post-encounter recovery. Before spending, write the failure in one sentence: 'I died to chip damage,' 'I never saw the partner,' or 'my Crawler buff expired too early.' Buy the upgrade that changes that sentence on the next run.
Practical decision
Polentir adds Arcana choices, Grim Grimoire improves recipe planning, and Stardust Anvil opens gem-slot customization. Each system can remove a bottleneck that shop stats were previously compensating for. After one of these unlocks, refund and retest before buying more ranks of the old solution.
