Bronze

Proficiency - Decreases the regeneration time (Note: actually the cooldown) of Acute Mind. (49.5% + 0.5% per CA level decrease)
Insight - Additionally increases intelligence. (5 + 7.5 per CA level increase (?))

Silver

Defiant - Decreases the impairments and wounds. (20% + 0.5% per CA level)
Insight - Additionally increases intelligence. (5 + 7.5 per CA level increase (?))

Gold

Celerity - Increases attack and cast speed. (20% increase)
Easiness - Additionally decreases the regeneration time. (15% + 0.5% per CA level / 50.8% on CA level 1, 72.8% on CA level 50, 81.25% on CA level 100, ... linear increase of base value)

The following skills will affect this combat art:

Casting Acute Mind will actually reduce its own Regeneration Time (does not effect Cooldown Time), so later in the characters devolopment if setup for the best Regeneration times keeping the Spell up semi-permanantly will ensure a constant low regen time.
Even without the Insight mods, this CA will cause a large increase in damage of any activity calculated with the intelligence value. (non-weapon-based CAs, magic staffs).
Taking the Proficiency bronze mod will cause Actue Mind's cooldown (not the regeneration!) to decrease with additional runes. This will allow the duration of the skill to eventually catch up with the total regeneration time, allowing the skill to remain up semi-permanently. This does not occur until later in a character's development, approximately level 100.
