I have three attacks per round with a repeating crossbow. The repeating crossbow holds five bolts. On round one I fire 3 bolts. On round two can I fire twice and then QuickDraw a second repeating crossbow and take the last attack or is it lost?
Thanks.
Yup, you should be able to do this.
Assuming you drop the first repeating crossbow, store it somehow such as with a glove of storing, or fire the newly drawn crossbow one-handed, then absolutely you can do this.
I only make a point of this because keeping track of what happens to the extra weapons can prove significant for such things as unattended objects and area of effect damage spells.
