Wiki Immune System Deep Organ Cells From the Lymph Node down, each organ fields its own specialists: buffers, stealth hunters, factories that spawn more cells, and cells that rewrite the floor under you.
On this page 12 Helper T Cell Thymocyte Lymphoid Progenitor Follicular Dendritic Cell Goblet Cell IgA Plasma Cell Stellate Cell NKT Cell Megakaryocyte Myeloblast Astrocyte Resident Memory T Cell Hangs back and pulses cytokines that make every nearby cell faster and harder-hitting. Several helpers keep a whole room buffed.
Base stats: 40 health · 95 speed · 6 touch damageKeeps 220–320 points away Cytokine pulse every 4.5 s, radius 220: cells inside move 35% faster and hit 30% harder for 4 s Organs: Lymph Node, Gut, Bone MarrowAlso the Follicular Helper T Cell boss's reinforcements, and grown from Lymphoid Progenitors From the Codex A CD4 T cell that coordinates the immune response, releasing cytokines that switch on other immune cells. HIV's main target.
Fun fact: Losing helper T cells is what turns HIV infection into AIDS.
Helper T Cell in the Codex Small, fragile young T cells that drift around you in packs. Every time you dash, every thymocyte nearby dashes straight at you too.
Base stats: 28 health · 85 speed · 7 touch damage (the smallest lymphocyte)Circles 150–230 points from you Copies your dash: every thymocyte within 520 points lunges at youAbout a third fail negative selection and die on their own after 6–14 s (FAILED SELECTION) Organs: Lymph Node (very common), BrainFrom the Codex A young T cell in training in the thymus. It is tested against the body's own proteins, and most fail and die.
Fun fact: Over 95% of thymocytes never graduate: they're eliminated for being useless or for attacking the body itself.
Thymocyte in the Codex Slow, weak and harmless at first, with a ring that fills over 6 seconds. When it fills, it becomes a full lymphocyte.
Base stats: 45 health · 45 speed · 5 touch damageKeeps 260–420 points away while its ring fills After 6 s: DIFFERENTIATED! It becomes a B cell, NK cell or helper T cell, already hunting you1 time in 10 it becomes a weakened Killer T clone instead Organs: Lymph Node, Bone MarrowFrom the Codex The parent cell of every lymphocyte: in the bone marrow it matures into B cells, T cells and natural killer cells.
Fun fact: One stem cell line can give rise to every kind of immune cell in your body.
Lymphoid Progenitor in the Codex Doesn't move. It sits in a web that slows you and fires rotating rings of slowing shots.
Base stats: 90 health · never moves · 8 touch damageIts web (radius 150) slows you to 40% speed while you're inside Every 3 s within 420 points: a ring of 6 slowing shots (7 damage each)Can't roll the Swift, Enraged or Splitting affixes Organs: Lymph Node, BrainFrom the Codex A web-like cell in lymph node follicles that holds antigens on its surface for B cells to inspect.
Fun fact: FDCs can hold on to antigens for months, helping build long-lasting immunity.
Follicular Dendritic Cell in the Codex Lobs blobs of mucus at where you're standing: a warning circle, then a sticky puddle that slows you.
Base stats: 70 health · 50 speed · 8 touch damageOnly walks toward you when you're more than 260 points away Every 2.1 s within 480 points: a 0.8 s warning circle, then the glob lands for 8 damage if you're insideLeaves a sticky patch for 7 s that slows you to 20% speed Organs: Gut; also the Paneth Cell boss's reinforcementsFrom the Codex A cup-shaped cell in the gut and airway lining that secretes mucus to trap microbes.
Fun fact: Goblet cells can refill and release mucus within minutes.
Goblet Cell in the Codex Keeps its range and fires spreads of sticky, slowing antibodies.
Base stats: 60 health · 70 speed · 6 touch damageKeeps 260–360 points away Every 2.4 s while it can see you within 460 points: a 3-shot spread (7 damage each) that slows you Organs: Gut, LiverFrom the Codex A plasma cell that makes IgA, the antibody that guards mucosal surfaces like the gut.
Fun fact: Your body makes more IgA than all other antibodies combined: several grams a day.
IgA Plasma Cell in the Codex Weaves toward you, leaving patches of scar tissue behind it. The floor gets harder to move on the longer it lives.
Base stats: 75 health · 70 speed · 12 touch damageDrops a patch of scar tissue (fibrosis) every 2.2 s Scar tissue lasts 7 s and slows you to 20% speed Organs: Liver; also the Kupffer Cell boss's reinforcementsFrom the Codex A star-shaped liver cell that stores vitamin A; when the liver is injured it turns into a scar-making cell.
Fun fact: Stellate cells are the main driver of liver fibrosis and cirrhosis.
Stellate Cell in the Codex Almost invisible while it stalks you. It appears with a '!' right next to you and lunges for heavy damage, then fades again.
Base stats: 70 health · 120 speed · 14 touch damageBody is only about 12% visible while stalking Within 160 points: decloaks with a '!', winds up for 0.4 s, then lunges at high speed2.2 s between strikes Organs: Liver, Bone Marrow, BrainFrom the Codex A T cell with natural killer features, abundant in the liver, that reacts within hours.
Fun fact: Up to 30% of the liver's lymphocytes can be NKT cells.
NKT Cell in the Codex Huge and tough, it keeps shedding platelet swarms and bursts a ring of fragments when you get close. Kill it to stop the platelets.
Base stats: 180 health (the toughest regular cell) · 48 speed · 14 touch damageBuds 3 platelets every 5 s, up to 9 alive at once Within 190 points, every 2.2–3.4 s: it swells, then 0.4 s later bursts a ring of 10 fragments (7 damage each), so hugging it doesn't workOrgans: Bone Marrow; also Hematopoietic Stem Cell summonsFrom the Codex A giant bone marrow cell that sheds thousands of platelets from its edges.
Fun fact: One megakaryocyte can release up to 3,000 platelets.
Megakaryocyte in the Codex Fast and fragile, it rushes straight at you, and when it dies it bursts into three neutrophils.
Base stats: 55 health · 105 speed · 9 touch damageOn death: three half-health neutrophils burst out, already huntingKilling it point-blank is risky; kill it from range Organs: Bone Marrow; also the Hematopoietic Stem Cell boss's reinforcements and summonsFrom the Codex An immature white blood cell that will develop into a neutrophil or other granulocyte.
Fun fact: Too many myeloblasts in the blood is a sign of acute myeloid leukemia.
Myeloblast in the Codex Hangs back and wraps up to three nearby cells in protective shields, refreshing them as they break.
Base stats: 85 health · 60 speed · 6 touch damageKeeps 240–340 points away Every 5 s: shields up to 3 unshielded cells within 260 points, each shield worth 35% of that cell's healthNever shields bosses Organs: Brain; also the Microglia boss's reinforcements and summonsFrom the Codex A star-shaped brain cell that supports neurons and helps form the blood-brain barrier.
Fun fact: Astrocytes are the most numerous cells in the brain.
Astrocyte in the Codex Teleports right next to you every few seconds and fires a five-shot burst, with little warning.
Base stats: 60 health · 90 speed · 10 touch damage (it walks at half speed between blinks)Every 3.2 s within 600 points: blinks to a spot about 110 points from you0.35 s later: a 5-shot fan (8 damage each) aimed at you Organs: Brain; also Microglia summonsFrom the Codex A memory T cell that stays in a tissue for good instead of circulating, ready to strike reinfections immediately.
Fun fact: Brain-resident memory T cells can persist for years after an infection.
