Spinning blade trap Redlake Fort
What the scythe wall trap may have looked like
Wall Scythe Trap (says CR 4 in the Giant slayer book but when I looked it up on PFSRD it should be a CR7)
type: mechanical DC 25 perception to locate, DC 30 Disable device
Effect: Atk 6 [x4])
Here is my vision of what the scythe wall trap may have looked like: two or three spinning blades coming from various directions inside the corridor that automatically re-set. If you recall the movie I grabbed these pictures from (Indiana Jones and the Last Crusade), then you will also re-call several people died before Indie was able to overcome the trap.
