Bastila was actually pretty unremarkable, besides Battle Meditation, the only reason she is even on the map is because of her partner, Revan.
What about Bastila? Bastila had very, very powerful force us, (KotOR of course). She had Battle Meditation which canonly would turn the tide of battles, especially the Star Forge battle which the Sith were winning by a mile, and then when she used her battle meditation, the Republic fought back and won. This was just one of her abilities.
