I'm not particularly adept (heh) at 5th Edition in general, so let me try and break it down so I understand.
Thank you for helping me understand, I wasn't a fan of 5e so I didn't pay much attention to it, but Level Up feels much more colorful and fun.
- Extra Attack gives you two attacks for one action.
- Two-Weapon fighting allows you to spend your bonus action for another attack with your off-hand weapon. If you also have Extra Attack, your bonus action nets you two attacks with your off-hand weapon.
- Flurry of Blows allows you to spend Exertion as a bonus action for two unarmed attacks.
- Unlikely Wield requires that you are using Light weapons (up to three?), but your bonus action doesn't limit you to two off-hand weapon attacks. You can use whichever of your three light weapons you want.
- If so then...
- Flurry of Blows is slightly better than Two-Weapon Fighting from 1st-4th level since for the expenditure of Exertion, you do get one more attack.
- Flurry of Blows does nothing from 5th level on because Two-Weapon Fighting does the same thing and is free.
- If not, then...
- Flurry of Blows is better than Two-Weapon Fighting from 1st-4th level since they are attacks you don't have to be armed or have an offhand weapon to make AND you get one more attack than you would have.
- Flurry of Blows is kind of irritating from 5th level on because Two-Weapon Fighting does ALMOST the same thing and is free and then it becomes "Why is it harder to punch things twice instead of stab things twice?."
