Crypt of the NecroDancer: Trapdoor Fights
Crypt of the NecroDancer: Trapdoor Fights
Some of examples here assumes it's boss trapdoor and you want to enter the fight asap.
For non-boss trapdoors, you can just dig/bomb out if you have enough tier/plenty (especially on Dorian/Eli, or Melody/Monk after shop resets).
You can use pulse if you have, unless it's Windows non-boss Bard trapdoor.
