Exocortex-combat tracking

[Grumpus]

Does the ability to treat BAB=Level happen at level 1? or at level 3?

The first sentence is clear that you get profiencies right away at level 1.

The second sentence is clear that you get specialization at 3rd.

It is unclear to me whether the next sentence is also abilities that come online at 3rd level. Or if they are active from the beginning.

Separate sentence, so not limited by the previous sentence. Or to put it simply, it applies from 1st level because it's part of Combat Tracking, not part of Weapon Specialization
