Blood Dungeon Wyrm and the Leech Trophy
Leech is a Steam achievement: defeat Wyrm in under 30 seconds. It is not a playable character.
Leech is not a bunkmate. Steam’s achievement named Leech unlocks when you defeat Wyrm in under 30 seconds. Older guides that told you to “main Leech” confused that trophy with a character. Blood Dungeon has nine bunkmates. Public kits: Gun Man, Barbarian, Skinja, Baby, Hypnomancer, Leggy, Bug. Hotfix names: Powder Keg and Revivalist. Full roster: Bunkmates. Full trophy list: Achievements.
The game launched 25 August 2026 as single-player only. Demo footage and 9Puz treat Wyrm as the first Catacombs boss with a long health bar across the bottom. The retail client’s boss bar and quest panel are the authority if wave timing differs from an old demo recording. This page will not invent a wave number that Steam does not print.
How the fight actually plays
Wyrm is a long body. 9Puz’s beginner notes: do not chase the head into a closed pocket. Keep the Catacombs loop. Let the body cross your working lane. A reversal that was harmless against bats can put several segments on the same ladder. Move early when the next junction starts to close. Movement is the survival skill. Auto-fire still means you route, you do not aim.
Weapons that hit a long body without you standing in it:
- Bounce balls — PC Gamer’s first-boss shredder. Ricochet fills the loop while you stay on the route.
- Machine gun — Gun Man’s teacher. Honest if you have already opened a second slot. Weapons.
- Laser — single-target uptime if you can keep the beam on segments. Shield (ten enemies on one beam) is a different trophy.
Do not empty your magazine chasing the head off your practised circuit. Beat Bosses is the general pattern page. This page is the speed-kill overlay: damage plus a clean loop, not sightseeing for keys. Chests & Keys can wait. A locked door is not the Leech condition.
A Leech run that does not waste Bones
- Learn cling until Catacombs is boring. Getting Started.
- Bank Bones at the Dogmancer for a second weapon slot and hearts. A naked first night is a learning death, not a 30-second clear.
- Take bounce or a long gun in the first cards if they appear. Reroll Gold when you are one named piece away — Synergies.
- When the Wyrm bar appears, stop looting. Keep the two-exit route 9Puz describes: both directions without a blocked ladder.
- If the clock blows past 30 seconds, finish the fight anyway. Bones still bank. Leech can wait for a denser gun.
Slow Enemies is a different speed trophy: Bone Snake under 30 seconds. Do not mix the names. Polygon named a Bone Dragon; treat that as review language, not a third Steam title unless the client says so.
What this page will not say
It will not invent a Leech bunkmate, a whip owner, or a Bone price to “buy Leech.” It will not invent oxygen litres or a numbered patch 1.0.1. Messhof’s news titles are hotfix and hotfix 2. Crashes: Troubleshooting. Streamer Mode does not change Wyrm. Compare kits: Character Compare.
Wyrm is a long Catacombs boss. Leech is a clock. Keep the loop, stack bounce or a beam, and ignore any guide that still sells Leech as a playable character.
