The holy cone only existed during part of round 5 and all of round 6. It could only be found in churches at a very low find rate and broke quickly, but did a ludicrous 9 damage with each hit.
Alex created it as a gift (”As a thank you for starting the first in-game religion in Q2019, and making my girlfriend laugh her ass off...”) for the Conists, a traffic-cone-wielding group from the era.
