I made several of these and have them hotkeyed...but when i click on the on a revealed trap using the springer, nothing happens at all...
Why do you want to disarm floor traps anyway? If you're capable of detecting them then I find your character automatically finds a path around them unless you click directly on the trap. Maybe trap springers don't work on traps not attached to a door/container, I've never really tried them out.
The BMC mine is where I learned that the Flow Spectrometer consumes batteries. I'd rather use them in my charged staff.
Correct, Trap Springers only work on traps places on doors and containers. If fact, they are explained to work that way in the description in their schematic. The only way to disarm a floor trap is with the Disarm Trap skill.
