Is it just me or is two weapon fighting just broke! I can never get it to work, main hand attack works fine but after the attack the off hand weapon always says out of actions but I thought it was a bonus action? I got 2 weapon fighting at level 2 for my ranger but it has never worked and you can't use 2 longswords or scimitars either which doesn't make any sense but it will not matter if it's broke anyway.
Most of the time you will automatically perform your bonus action off-hand attack if you still have a bonus action left when you make your basic attack.
