looking for a high crit range crossbow or other range weapon

[Nosta]

so i'm looking for a range weapon with a threat range 18-20 or a x4 multiplier
I want to go evil outsider hunting. I'm building an exorcist style character and I plan to use a range weapon with sacred and sacred burst so I like high crit

any one know oif such a weapon or a way to improve a light crossbow?

Your best bet is a Great Crossbow (RoS p153) which has a full round reload with 18-20/x2 crit. Another strong choice would be a War Sling (RotW p165) with Skiprock ammunition that has a 20/x4 crit. Other choices would include the Chatkcha (DR319 p40) which is a thrown weapon with 18-20/x2 crit. A Glot (Frost p76) can be skipped and bounced at range with a 18-20/x2 crit. A Razor Skipdisk (Frost p76) can be skipped and slid at range with a 18-20/x2 crit.
