A young invisible beast…
Adjust the strength of the Energy-conductor ability based on the strength of the PCs. For newer characters, reflect only 1 damage, while more advanced characters can take the full blow. Narratively, the stronger the beast, the more powerful it becomes. You should describe the glowing absorption of energy and discharge when melee attacking so the PCs understand to not auto-fire on that thing if they don’t want to die…
The beasts feed on underground purple phosphorescent mushrooms that are growing in caverns near small ponds. There are subspecies that are known to be living in forests and jungles as well.
The beasts are harvested to power the Voiceless One’s stealth technologies.
May always use Vigilance when making checks to determine initiative.
Upgrade the difficulty to hit twice for ranged attacks and once for melee attacks (when already engaged); Sensors does not help to detect the beast; upgrade perception and vigilance checks twice when someone tries to see the beast.
Can see in the dark and other invisible beings.
Energy weapons are only an annoyance to the beasts, each successful shot hit for a maximum of 1 wound.
Each energy weapon’s hit makes the beast add up to a per soaked wound to its next attack, discharging some of the absorbed energy. This is cumulative.
