Talent description: Two-handed weapon attacks consume (10%, 17.5%, 25%) less Stamina per attack.
But, neither the Greatsword nor the Halberd are affected.
With 164 Stamina, I get the same performance, whether I have the talent or not.
Greatsword: 5 regular attacks or 3 power attacks = stamina empty
Halberd: 4 regular attacks or 3 power attacks = stamina empty
