Saryn — Miasma Bloom
Endgame build. Infect the room, then Miasma. Viral hits twice as hard on spore hosts. This is a burst, not a press-4 simulator.

Wrong drop or mechanic?
Don’t build this yet
First Pox first
This loadout sits at Endgame. It wants Forma, Helminth, or shards you may not have. Play the Starter until those systems are open — then this page is the upgrade, not the homework.
Open First PoxWhy this build?
Endgame for Sanctuary Onslaught, dense Exterminate, people who want a caster Saryn
Health: Not yet — Helminth, Steel Path, or Archon Hunts still closed. Play the Starter.
- Miasma is a nuke only on infected hosts. The tooltip is not a suggestion.
- This is slower than melee Lash in a hallway and faster in a circular tile full of infested.
- Transient Fortitude hurts Duration. Do not drop Continuity or the ticks vanish.
Don’t use this for: new accounts · Star Chart only · solo level-cap
Specialised investment for hard content
You don’t need the shards to run the loop. They are a later ceiling, not a gate.
Bring: No exalted — Miasma is the nuke. A primer is optional once Spores are on everything. Casting speed is DPS.
Alternative if…
- Star Chart only → First Pox
- New account or low investment → First Pox
- This is too much Forma / cost → Garden of Knives — Optimised

Your note, in this browser. Separate from Codex verification — the stamp on the card is editorial, this is yours.
Readiness
Inventory unknown
Not checked — add your collection. You have not failed a test.
- Required mods 0/9 · required — 0/9 named
- Forma 0/5 · required — 5 on the card. Codex does not track installed Forma.
- Helminth · optional — Not required
- Arcanes · recommended — 0/2 recommended
- Shards · optional — Optional unless the card says a breakpoint
Investment: 5 Forma · Reactor · 2 shards · 5 specialised mods. Typical farm ~4–6 hours. Trade if a route is vaulted.
Codex Checked · Compared against current game data for this update. · Update 43.5 · 5 Sept 2026 · PC · Current
Medium confidence. A solid recommendation with more situational dependencies. Confidence is not verification. Verification is separate: Codex Checked against Update 43.5.
