The Bomboozler

This specialized bomb was designed to disrupt dragons and dragonkind. Recognizing that the device violated the Covenant its creator quickly sold their prototypes to the highest bidder. The Bomboozler is a palm-sized gnomish sphere covered in various cones, knobs, and dials. Once activated it lets out repeating flashing concussive and sonic blasts.   Any dragons within 100 ft. of the bomb must make three saving throws as soon as the device is active and again at the start of each of its turns. The effects last for one round each.  

• DC 17 Constitution saving throw or become blinded and deafened.
• DC 17 Intelligence saving throw or be afflicted by the Feeblemind spell.
• DC 17 Wisdom saving throw or become frightened.

  The Bomboozler will run until it stops and is then broken. Because the bomb is a prototype it is unclear how long its effects will last, roll 1d4 to see how many rounds it will continue.
