Fire Ant Colony
Colony that responds to threat as a single defensive unit. Alarm pheromone commits the full soldier caste at once, and the injected formic compounds persist in tissue long past the encounter.

The best you can use
Sign in and set up your character to see the best gear you can use.
Estimate with the game's fight rules: 2d10 plus accuracy against a defense of 6 plus armor modifiers; a critical hit (two tens or 10 over the defense) deals ×1.5; damage minus the armor for that damage type, at least 1 per hit; base health 60; a turn every 10 s. Natural defense, skill bonuses, range and terrain are left out.

Codex entry
- Entry 1
Colony responses propagate faster than pheromone diffusion can account for. Institute entomologists recorded coordinated leg tapping through soil, paired with synchronized red-orange light from bacterial symbionts in the abdomen. The entire mass changes direction within seconds.
- Entry 2
Caravan crews say fire ants do not scatter when burned. Workers pile into hooked masses, using dead ants as footing across hot ground, then collapse and reform on the far side. At night the moving shapes glow like banked coals.
- Entry 3
A buried emergency-radio cable near an abandoned relay station was found packed solid with dormant fire ants. When technicians energized the line, the colony began pulsing in sequence with a recorded 1988 test signal.
