Biosanctic Broodsurge — Genestealer Cults Detachment Guide

The Broodsurge rule supercharges your melee core — broadly, Aberrants, the Biophagus, and Purestrain Genestealers get better on the charge, with bonuses in the neighbourhood of improved charge rolls and extra attacks when they slam in. The intent is a reliable alpha-strike in combat: these units are already dangerous, and the detachment makes their charge turn hit above its weight. Because your ambushes let you dictate when and where the charge happens, you get to pick favourable fights. Confirm the exact charge and attack bonuses in the current Faction Pack.

Expect stratagems that add lethality or survivability to your melee units at the point of impact — damage upticks, re-rolls, or a defensive shrug to help fragile hitters survive to swing. The playbook: commit a stratagem the turn your Aberrants or purestrains charge a priority target, not before. If you can only break one enemy unit this turn, stack your resources on that fight. Save any 'fights first' or damage-boost effect for a charge you can't afford to whiff. Check current CP costs in-app.

Broodsurge enhancements typically boost a melee character or the unit they lead — think added attacks, better armour penetration, or resilience to carry the character through the counter-swing. Put your survivability enhancement on the leader you most need alive to trigger the buffed charge, and your damage enhancement on the model joining your hardest-hitting squad. As always, exact enhancement names and values are Faction-Pack-defined; verify before you rely on a specific number.

Aberrants are the poster boys — heavy, hard-hitting brutes that the detachment rule was built around. The Biophagus is the enabler, buffing the brood with mutagens. Purestrain Genestealers bring speed and volume of attacks. Support them with cheap hybrid Battleline to screen, hold objectives, and soak fire while the hammer units get into range. A Patriarch or Primus can lead and add threat. Deliver the hammers via ambush so they arrive fresh and in charge range.

Take Biosanctic Broodsurge when you want to win the fight phase outright and enjoy piloting a melee alpha-strike. It's strongest into armies that don't want to be charged and can be broken in a turn. It's more demanding than Host of Ascension — you must land charges to get value — so play it once you're comfortable sequencing ambushes. It also DP-pairs naturally with a hybrid-horde detachment that supplies bodies to screen your monsters.
