Edit: A lot of people say, that GWM needs a melee weapon attack, but they miss Jesses point: While GWM requires a melee attack with a heavy weapon, Sharpshooters only criteria is an attack with a ranged weapon (not a ranged weapon attack).
Jesse bases his claim on the fact, that a crossbow is still a ranged weapon, even if used as an improvised weapon for melee combat. That’s why it deals 1d4(!)+20 damage.
(It works with any ranged, heavy weapon btw., so Longbow qualifies too.)
Of course Jesse is playing the devils advocate here and of course, no somewhat sane Walter will allow this in any campaign ever, as it’s obviously not the intention behind these feats. But you could read it that way and that’s Jesses (paperthin) point.
Besides: he finds the image of a barbarian running around recklessly smashing a crossbow over everyone’s head to just be hilarious.
The meme community hasn't read the rules
Reading in my ttrpg? Impossible. All that matters is the dm regurgitating the rules for the players.
Literally every time someone posts with this Walter and Jesse meme format, it is the dumbest shit I've ever seen. It makes me lose brain cells instantly and desperately wish I had unsubbed from this community months ago
