How is throwing distance computed for improvised weapons? I have a player whose favorite tactic is chucking oil flasks at opponents and lighting them on fire, so this comes up a fair amount.
I haven't found anything in the PHB that covers throwing things, nor in the DMG. It seems to me that things which aren't balanced for throwing would have less distance than things which are (20/60 for dagger, handaxe, etc). Are there explicit rules, or am I on my own?
