I've captured a FB toad with noxious secretions, boiling at room temperature. Such secretions work even when the beast is caged, so it's a near perfect bioweapon. Handling dwarves would be affected, so before capturing I was observing the beast, when it came near a band of troglodytes. They were nauseous, but recovered. To be sure, after capture, I dropped two laboratory cats to the corridor with the beast. One of them was incapacitated and covered the corridor with vomit, but also recovered. Then the gobbos attacked, and zombies, and I had much fun observing them chasing merchants and stuff. When I returned to the lab cats, the second one was dead and in a cage - apparently he was incapacitated so much that he triggered cage trap. After that I dropped other laboratory animals, like pigs and birds. None died, only vomited. Death of the lab cat remains mystery.
If it was a combat, I would get a detailed description of what happened and how. But it wasn't a combat, and there are no reports of vomiting or sickness or collapsing or anything. This limits usefulness of other research. I've built a whole biocontainment facility, crossed with arena, training centre, incinerator and obsidian caster, but I'm unable to test the effects of FBs syndromes easily, due to the mentioned limit. Is there any way I can enable combat-type reports for non-combat events? After all the only difference is the method of initiation. In combat it is initiated by something attacking something else. In syndromes, it is environment which attacks.
