Route planning: choose the next requirement, not the richest path

A practical map heuristic for elites, upgrades, shops, recovery, and Act 3 boss insurance.

Start with the next test

  • Name the next elite or boss requirement: front-loaded damage, AoE, block, scaling, or cleanup.
  • Choose rooms that improve that missing requirement before maximizing theoretical gold or relic count.
  • Recalculate after every card reward, relic, potion, and large HP loss.
2

Value flexibility

  • Prefer paths with a late fork so the run can choose aggression or recovery after seeing rewards.
  • A shop is strongest when you have enough gold and multiple problems it can solve—not merely because it is on the map.
  • A rest site is an upgrade node only when the remaining HP and upcoming fight allow it.
3

Elite decision rule

  • Take the elite when the current deck already passes its likely damage and defense check, not because a relic might rescue it.
  • Count potion value as part of the fight plan. A potion spent to secure a relic and preserve HP can be correct.
  • Skip chained elites when one bad draw would force a rest that removes the route’s expected value.

Act 3 insurance

  • Before locking a route, check the visible boss and buy or upgrade the missing answer.
  • For Aeonglass, prioritize efficient block, compressed damage, Artifact stripping if needed, and hand cleanup.
  • Do not add speculative cards late unless they solve a named boss or elite failure mode immediately.
