Blood Dungeon Weapon Synergies

Blood Dungeon is an auto-fire bullet-heaven platformer: you steer, jump, and climb while every equipped weapon shoots without a trigger pull. Power in a run comes from the cards you accept when you level, the bunkmates already unlocked, and the extra weapon slots you buy with Bones. This page records synergies that reviews and Steam achievements actually name. It does not invent damage-per-second figures. If you still need the loop explained in order, read How to Play. For ranked types and starter kits, use the Builds Hub, the weapons list, and loadout templates.

How level-up cards work

Fill the Blood bar and the run pauses on two or three random cards. Aftermath reports that coins can reroll that hand, so Gold is not flavour text — it is a way to fish when the offer is noise. You cannot choose the pool. You can skip a generic buff if you are one named piece away from a combo you already committed to.

Steam lists three resources: Gold, Blood, and Bones. Blood is the in-run experience meter. Gold pays rerolls and other in-run spends. Bones survive the death screen and buy extra weapon slots at the Dogmancer — the Bones and Dogmancer guide is the permanent half of every synergy. More auto-fire lines stacked at once is the simplest combo in the game: a circling melee toy plus a gun covers the pack that has already closed in.

Plan those slot purchases with the player tools before you dump a session’s Bones in the wrong order.

Confirmed weapons and achievement thresholds

Coverage and Steam achievements name toys and challenge numbers. Treat those numbers as goals on a trophy, not as a typical shot.

Machinegun. Gun Man’s documented starter. Double Deagles asks you to fire 25 shots before a reload. Bullet Time is tied to a maxed Machinegun. The family cares about magazine uptime and about investing until the gun is marked max — not about a hidden element.

Magnum. Baby’s default long-range pistol. Stagger asks for a 700 hit in one Magnum shot. That is an achievement bar, not the damage you should expect every trigger. When you want a simple hard-hitting auto-fire line, this is the clean pickup.

Laser. Shield asks you to tag 10 enemies with one beam. Line enemies up; do not treat it like a shotgun.

Bounce balls, basketball, volleyball. Reviewers call the bouncing ball — basketball in some write-ups — a boss shredder. Life Insurance asks you to keep 20 bounce balls in play at once. The combo is ricochet plus count, not one fat marble.

Shotgun. Tied to Skinja in coverage; spread can grow. It wants packed bodies, not a sniper lane.

Circling swords and the whip. Orbits that occupy the tile you stand on. Dual circling swords are the Barbarian’s documented starter. The whip is a confirmed circling melee toy; this page does not invent a bunkmate owner for it. Pair either with a ranged line so a swarm that reaches you is not a blank screen.

Spiderwebs. Leggy’s kit. Slow Ring asks for 25 enemies in webs at once. Webs slow, trap, and double as platforms in water — see movement and Flood.

Turrets. Extra auto-fire that holds a corridor while you climb. Coverage names them as a tool in the box; treat them as a line that stays put while you move.

Axe. The Grenade achievement asks for 10 kills with one Axe. Wait until a cluster overlaps the swing.

Harpoons. Flippers asks you to retrieve 25. Throw, recover, repeat — it is not a fire-and-forget gun.

Zombie Ring. Defibrillator asks for 10 zombies at once. Pressure and bodies, not a beam.

Gas Grenade. The Hypnomancer’s starter and a lingering denial cloud once that bunkmate is in the roster.

Jetpack / flight. Bug is the bunkmate public coverage ties to flight. Jetpack is also a named Steam trophy for staying airborne. Both change which cards matter: air time and angle, not ground kiting. Details sit on the movement guide. Named trophies for these toys are listed on achievements.

Arena and body synergies

Aftermath describes an oxygen-low fire-rate upgrade in water stages. That is a Flood synergy and not a guaranteed drop. If the card never appears, you still play Flood with breath, webs, and positioning; you do not reset the arena until a mythical water card shows. Read Flood and the Arenas hub before you treat a water modifier as a build tax.

Polygon describes cooldown reduction at full health and while standing in a spawned circle. Those are placement rules as much as item rules: keep hearts topped and step into the circle when it appears. A Daily Dungeon run is a short place to practise that without staking a long clear.

Game Informer reviewers rerolled for a double-everything upgrade. When that card exists in the hand, coins are for that — not for a third minor stat. It is not on every level-up.

Bunkmates and the drop pool

Unlocking a bunkmate can add their starting weapon to the drop pool. That is the long-term reason to open the roster, and it matches what this wiki already states. We do not invent a full mapping. Public coverage already ties the machinegun to Gun Man, circling dual swords to the Barbarian, shotgun to Skinja, Magnum to Baby, Gas Grenade to the Hypnomancer, and webs to Leggy. Bug is documented for flight, not for a named starter gun. Whip, bounce balls, laser, turrets, axe, harpoons, and Zombie Ring sit in the toy box without a complete public owner list. Leech is a Steam trophy, not a bunkmate — do not assign the whip to that name. The rest of the roster lives on Bunkmates.

Weapon slots still come from Bones at the Dogmancer. Extra lines of auto-fire are how the toys above stop starving each other.

How to spend a level-up

1. Fill a missing range band (orbit plus gun, or gun plus denial) before stacking a third copy of the same idea.
2. Spend Gold to reroll when you are one named card away from a combo you already built toward.
3. Do not schedule Flood’s oxygen fire-rate card, Polygon’s circle, or the double-everything upgrade as if they were quest rewards.
4. After the run, buy slots, then test the wider pool in a normal arena or a daily dungeon.

The weapons and loadout pages stay practical kits. This page is the table rules: what the cards can do, what trophies prove exists, and what no reviewer promised as a guaranteed drop.
