If a cloud of Acarus Adamas are prevented from returning to hyperspace within a few hours, they die. If this happens, their stolen ship can be recovered, and the organisms themselves are valuable on account of their diamond shells. The remnants of a failed Diamond Man attack is one of the luckiest finds a fortune seeker can make.
The biology of the organisms is very complicated. Every microbe in the swarm communicates with its neighbors via radioactive bursts. However, they can only feed when assembled into their signature polygons, or ¨dice,¨ which use the ingested materials to create more microbes. It is also in the ¨dice¨ form that they can experience the narcotic effects of ship fuel.
When engaging Diamond Man, radiation gear is a must. Use wide-burst weapons, like plasguns or explosives. If you´re fighting them in a place that still has atmosphete, use incendiaries. Fighting, however, should only be a last resort; if at all possible, flee. If you can´t do that, try to bargain for your life and hope it can understand you and feels like listening.
If attacked in normal space, you can at least teach the swarm a lesson by firing on its stolen wreck. Even if it kills you, you´ll have sentenced it to death in a few hours if its FTL engines are destroyed.
