Apothecary Biologis Guide — Space Marine Medic Support

What Is an Apothecary Biologis?

The Apothecary Biologis is a Space Marine Apothecary in Gravis armour, released in the Leviathan launch box in 2023. He fights alongside the Chapter’s heaviest Primaris infantry. Like every Apothecary he is charged with recovering the gene-seed of the fallen, but his speciality, as the name suggests, is studying the biology of the enemy, which makes him a natural fit for an army set up to fight the Tyranids.

On the tabletop, though, he is not a healer. Unlike the standard Apothecary, his datasheet has no Narthecium; instead he joins a Gravis squad and gives its attacks Lethal Hits against non-Vehicle targets.

Apothecary Biologis Lore

Every Space Marine Chapter keeps a corps of Apothecaries who act as both battlefield medics and guardians of the Chapter’s genetic legacy. Their most important duty is recovering the progenoid glands, the gene-seed, of fallen battle-brothers. That gene-seed is what lets a Chapter create new Space Marines, so without it a Chapter can’t replace its losses.

The Biologis takes this further. As well as caring for his brothers, he studies the bodies of the enemy, cataloguing their weaknesses and turning what he learns into an advantage on the battlefield. Against a foe like the Tyranids, a living weapon whose biology keeps adapting, that knowledge is especially valuable.

His Gravis plate lets him keep pace with, and survive alongside, the slow-moving, heavily armoured Gravis squads he supports.

Datasheet Overview

The Biologis is a support character. His value comes from what he does for his squad, not from his own damage output. Rather than repeat numbers that change with every balance update, here is what his kit and role amount to. Check the exact rules on his current datasheet in the Warhammer 40,000 app.

No healing: The Biologis has never had a healing ability on the tabletop, in 10th or 11th Edition. If you want a squad healed, the standard Apothecary’s Narthecium (it heals D3+1 wounds in your Command phase) is the rule you are looking for.

Vivispectral Analysis Targeting: the unit’s attacks have [LETHAL HITS] against non-Vehicle targets. In 10th Edition he granted Lethal Hits through Surgical Precision; the 11th Edition codex keeps the effect but limits it to non-Vehicle targets. That’s the main reason to take him.

Protection: 11th Edition has no “Look Out, Sir” rule. Instead, attacks against an attached unit are allocated in groups, and character groups always come after the bodyguard models. While any of his squad are alive, the Biologis is the last to take damage, unless the attacker has a Precision weapon (or uses the Epic Challenge Stratagem in melee), which can target a visible character directly.

Note: Always check the current datasheet in the Warhammer 40,000 app or your codex, and the Munitorum Field Manual for points, as abilities and costs change with balance updates.

Which Units Can the Biologis Join?

The Biologis joins Gravis squads: Aggressor Squads, Eradicator Squads (with melta rifles or heavy bolters) and Heavy Intercessor Squads, plus the Deathwatch Indomitor Kill Team. Check his current datasheet in case a balance update changes the list.

In 11th Edition, a bodyguard unit can take one Leader and one Support character. Both the standard Apothecary and the Biologis are Support characters, so the Biologis can share a squad with a Gravis-armoured Captain or Lieutenant leading it.

Heavy Intercessors

Heavy Intercessors are the most natural home for the Biologis. They are a durable, multi-wound squad with heavy bolt rifles that are built to sit on objectives and keep shooting. Lethal Hits on a steady stream of heavy bolt rifle fire makes them far better at grinding through tough infantry. It’s a balanced pairing that gives you value both ways.

Eradicators

Eradicators come with melta rifles or heavy bolters. Because his Lethal Hits don’t work against Vehicles, he adds little to melta Eradicators hunting tanks, but he helps against monsters and elite infantry, especially with the heavy bolter version.

Aggressors

Aggressors fire a lot of shots at short range with boltstorm or flamestorm gauntlets, so any buff to their attacks applies across a lot of dice. A squad of Aggressors with a Biologis on a midfield objective is a tough block that opponents have to deal with.

Tactical Usage

The Biologis is a passive force multiplier. Attach him to the right squad, keep the squad alive, and he earns his points every turn.

Protecting him

Because characters are allocated last, the main threats to the Biologis are Precision weapons and effects that ignore normal allocation. Keep his squad out of sight of enemy snipers where you can. Remember that in 11th Edition hidden units only count Infantry, Beasts and Swarm in light or dense terrain that haven’t shot recently. Gravis squads that want to shoot every turn won’t usually be hidden.

Picking targets

Lethal Hits only applies against non-Vehicle targets, so point his squad at infantry and monsters and leave enemy tanks to other units.

When the squad dies

11th Edition changed what happens when a bodyguard is wiped out. The Biologis doesn’t split off. He stays as the same attached unit, and any “while leading” style abilities he has keep working. Rules that trigger when a unit is destroyed only trigger when he dies too. But the unit’s starting strength doesn’t reset, so a lone Biologis is below half-strength and will need to take battle-shock tests. See our guide to how 11th Edition handles attached characters for the details.

Building Your List Around the Biologis

The Biologis works best in Space Marine armies built around durable Gravis infantry rather than vehicle-heavy lists.

Gravis-heavy lists

In a list built around Heavy Intercessors, Aggressors and Eradicators, the Biologis gives one of those squads the edge in a straight trade. Over a game, the extra damage from Lethal Hits adds up to a real advantage.

Objective-holding cores

In 11th Edition the objectives are terrain areas, and tough infantry that can stand in them and refuse to die win games. A Heavy Intercessor squad with a Biologis sitting on a central objective can hold it and still kill what comes to take it.

Choosing detachments

With 11th Edition’s Detachment Points, you can combine more than one detachment. If you’re building around Gravis infantry, look for detachments whose rules reward durable infantry holding ground, and check the current costs in the Warhammer 40,000 app.

Frequently Asked Questions

Apothecary Biologis vs standard Apothecary — which is better?

It depends on the squad. The Biologis is the offensive pick for Gravis squads; the standard Apothecary is the healer, with a Narthecium, and joins a wider range of non-Gravis infantry. Compare their current datasheets and points in the Warhammer 40,000 app before deciding.

Can I take multiple Apothecary Biologis models?

There’s no special “one per detachment” rule for the Biologis. How many copies of a datasheet you can take is set by the army-building rules for your game size, so check the current core rules and Munitorum Field Manual. In practice, one per Gravis squad you want to support is the most anyone needs.

Does the Biologis buff every weapon in his unit?

Almost. Vivispectral Analysis Targeting gives the unit’s attacks Lethal Hits, so it covers ranged and melee attacks, but only against non-Vehicle targets. Older 10th Edition summaries (Surgical Precision) don’t have the Vehicle restriction.

How do I paint an Apothecary Biologis?

The Biologis follows your Chapter’s Apothecary scheme, which for most Chapters means white armour. The narthecium and medical equipment on the model give you plenty of detail to work on: vials of coloured liquid, glowing screens and blood-stained instruments. A green or blue glow on the scanner makes a good focal point. Edge highlight the white armour carefully, as white is one of the hardest colours to paint cleanly.

Is the Apothecary Biologis worth taking in every Space Marine army?

No. He’s worth taking when your army includes Gravis infantry that wants Lethal Hits against infantry and monsters. If your army is mostly vehicles or non-Gravis infantry, a standard Apothecary or other characters will usually be a better use of points.

What armour does the Apothecary Biologis wear?

Gravis armour, the bulky, heavily armoured plate also worn by Heavy Intercessors, Aggressors and Eradicators. That’s why he fits naturally alongside those squads, both on the tabletop and visually, and why he looks noticeably bigger than a standard Primaris Apothecary.
