Dangerous slime light
Aqua's glow can harm light-sensitive Gloom even underground.
Active Aqua carry a cool glow of their own. For Gloom, this moving light is an environmental danger even deep at night or in a completely dark passage. It is stronger in an inner zone and weaker in an outer band. An Aqua merely visible beyond that range causes no harm.
Light without an attack
The effect is no ordinary blow. Group defence does not reduce it, and it triggers neither retaliation nor the same alarm response as an attacker. A Gloom may thus lose health while none of the Aqua involved is pursuing a combat target. The source moves with them, continually changing which ground is safe.
Several sources of light
Several Aqua can add to the effect, but a limit prevents a dense group from stacking damage indefinitely. The permitted combined effect is lower underground than on the surface. The connection is recorded in the Bestiarium only after one of your colony members actually experiences this light damage.
Two Aqua approached the passage from opposite sides. The Gloom withdrew, although neither moved to attack.
