When going through some builds of course I also tried the infamous throwing build. My char was based on Barbarian-Berserker 5/Rogue 3/Fighter-Eldritch Knight4 (you get Action Surge and bound weapons, but a bit meh because of low initiative) or Barbarian 8 /Rogue 4 (you get + initiative and three feats and a second bonus action) with a returning weapon. You could also simply go Fighter 12 with 3 throwing actions. Maybe there is even a better combo.

But: Both with the bound weapon from Eldritch Knight as well as with returning weapons (the pike of Act 1 or Nyrulna in Act 3) I had several severe failures, aka the weapon did not return, resulting in a wanna-be-uber-thrower-char looking quite stupid, without a weapon in the slot (I had always some spares in the inventory but ...).

Do you have similar experiences or is it perhaps something in my game/setup?
