Ok, but since you are only allowed to spend 1 endurance point, you lower the exertion by only 1 point, and you still cannot go over the max number of attacks for a weapon.
So for your knife example, the dagger entry in CRB says Exertion is 4 and Max attacks is 4.
So if you spend 1 endurance point to lower the exertion to 3, then you can still only hit 4 times becaus of the max attacks.
So for example, let’s say the base defense would be a 10 for your target… you would hit on a 10/14/18/22 normally
Now if you apply your endurance point to exertion for the knife… you would hit on 10/13/16/19.
In the grand scheme of things, that lowered exertion might allow one extra hit, maybe two.
And since the dagger only does 1d6 of damage, and melee kinetic damage is applied to each strike, you might do 2 - 6 points extra damage if you roll very well and the target is wearing light armor.
Now let’s take that to another extreme and say you are using the Long Spear (did not use 2 Handed Axe because that is still only 1 attack per segment).
With that same base defense of 10 for your target… you would hit on a 10/21 normally
If you apply that same point of endurance to reduce the exertion… you hit on a 10/20.
I fail to see how this is a game breaker in either of the extreme cases. I don’t see anyone getting torn to shreds in the manner you fear.
