Full DescriptionFound only in one location, (a very,very large virgin swamp), the Observer Beetle is a unique creature. An unassuming 1/2 inch long black bug with red markings. It feeds on anything that doesn’t move and lays its eggs in stagnant water (reproducing like normal beetles). When something unusual comes into the swamp (like adventurers)the beetles will begin to congregate near the interesting beings. When the adventurers camp, more and more beetles will gather around the camp. They normally do nothing. Normally.
If they are in the area of great good,great evil, or severely injured individuals; they act. They are in fact a hive mind with the abilities to sense good and evil as well as capable of casting moderate clerical or holy magic.
When they do spells it consumes hundreds of beetles; turning them into smoking ash.
They are fascinated by humanoids and will aid the very good and the injured who are not evil. Thousands of beetles will swarm an injured individual thereby healing him and then turn to dust. If you try to stop them more will just swarm in. Evil creatures will be attacked by spell (example the swarm will charm a deer and it would attack).They have no form of attacking otherwise.
The hive mind is very friendly to humanoids but has no real way of communicating. If the party is capable of communicating with the swarm, it will take several minutes for the hive mind to comprehend totally that it is being communicated with. It still is rather simple and has trouble w/abstract concepts other than good and evil.
It is a result of a toxic magic waste spill that connected a rare,dying out form of beetle to ambient energy of the god of nature.
You have to kill THOUSANDS of them for them to notice. Collected away from the swamp they quickly die.
It would take a HUGE disruption of the swamp for it to take action.
Start the swarm earlier in its existence when it doesn’t even know that it is good and develops its fascination with humanoids.
An evil force is trying to harness the power of the beetles -stop them. In my game, I had an evil force put them in one oz. potion of healing tubes to prevent them from dying,using them like a battery.
Try to find some way of spreading the beetles to other areas (tough to do).
