@JeremyECrawford Can a Barb/Fighter use a Dart in melee (w/STR) to benefit from Rage and Archery Fighting Style? Ranged weapon, melee attack

If you use a weapon in a way contrary to its design (melee attack w/ a ranged weapon), see "Improvised Weapons" (PH, 147). DM's call. #DnD https://t.co/L1jRs31HnE

@djmsmithImprovised dagger then? In accordance with the rules on that page? If you turn the page, you'll see the standard thing to do with a ranged weapon being used as a melee weapon.
