Question on Adept powers Options

[PraetorGradivus]

Improved Physical Attribute... is it like Attribute Boost, 4 separate powers, one for each physical attribute or is it just one power and every level you can make a different choice?

MASTER OF TAIJIQUAN
While people around the world practice taijiquan—a.k.a.
t’ai chi—for its defense-training and health benefits, an
adept mastering taijiquan flows like a river in combat,
especially with multiple melee combatants. He uses
the various attackers’ strengths to maneuver their
strikes against each other. When the adept successfully
blocks a melee attack from one attacker with Counterstrike,
he may choose instead to redirect that attack
against a second attacker. The second attacker would
have to defend against the first attack with the number
of hits equal to the adept’s Counterstrike test. The base
Damage Value is equal to the melee attack from the
first attacker. This mastery of kinetic energy only works
in combat against multiple melee opponents. You can’t
make an attacker hit himself, though you can taunt him
with the promise to do so. Prerequisite: Counterstrike
