Oh, pish-tosh! (Grumble, grumble!) I went and dug out my LML from under the pile of mags it was hiding under, but you owe me, big time! (Mutter, mutter!)
Kayedon's Thunderous Bolters: Two silver rods with mother-of-pearl handgrips, always found in pairs. Highly charged (Extreme++ Grade) with Supernatural energy, these weapons are each capable of firing up to six bolts per day (supernatural sixshooters), four per six-second round. The chance to hit and damage depends upon the range, as follows:
Range..........Chance To Hit.......Damage
Up to 50'.............90%..........1D20+1D4+16
51-150'...............70%..........1D20+1D4+12
151-300'.............40%...........1D20+1D4+8
The base damage (1D20) is Piercing and Blunt, and the 1D4+ is supernatural (Magic/Electrical), bypassing Slashing DR. Creatures which are especially vulnerable to either silver or electricity take maximum damage from the Magic/Electrical part, and are also knocked down, and must save or be Stunned for one round.
Each bolt is accompanied by a bright flash, and almost deafening thunderclap, as if from a lightning bolt. In a confined space (room, dungeon, etc.), the wielder (and anyone else within a 10' radius) will automatically be Deafened for one round (cumulative) for each bolt (so four bolts from each of the two wands equals eight rounds).
Effects of Stunned and Deafened are in the DMG.
(PS: Description not exactly as in the LML; I converted them to D&D terms).
