Fortunately, my PC is a gods damned packrat. I had a half million extra daggers, several great swords and so forth sitting in my camp chest. One quick detour and Astorion's got a shiny new dagger...

For real! I was all, "fuck me, are you kidding?", and scoured through my collective inventory (literally considering long-resting, in case I'd forgotten something in camp), but ultimately pressed on without closing that out. Meh. "Masterwork" at that level anyhow? Pfft.

Still. Wtf. 🤌🏼

I had to break off a party member and teleport to the druid camp to buy back a greatsword
