We rolled for stats in the campaign I'm in and I rolled 18 Str 17 Con and 15 for all other stats so I went half orc to bump my Str and Con to 20 and 18 for my fighter back up which started at lvl 5 (Party lvl). so I chose the Feat great weapon master to allow for more great sword damage and realized that if at lvl 20 I action surge with the four extra fighter attacks and so did my echoes that we would all attack 8 times and because of great weapon master you add proficiency bonus to heavy weapon attack damage. Ao I would get 40 extra damage and so would my echoes so 120 in total.
I think you have misread that class. 20th Echo Knight gets 2 Echoes, you get 4 attacks, plus 1 for Unleash Incarnation which can come from either echo. With Action Surge you will gain another 4 attacks and 1 more attack from one of the Echoes. So 10 attacks, assuming all hits gives 60 additional damage. (PB is +6 at 20th level.)
Echoes are not Simulacrums that act as a player character, they are much more restricted.
Still pretty good though!
I'm also at a loss what version of the game you're playing? You're referencing the 2014 rules with regards to gaining racial bonuses to ability scores, you're using a 2014.5 subclass, but you're taking the 2024 version of Great Weapon Master. If you wanted to go full 2014, you could deal +10 damage per attack, and, with a Haste spell, an Action Surge, an Echo, and twelve hits at a -5 penalty, you could do +120 damage, but you're just describing class features and feats working as intended.
