I play a Iktochi Mystic Seer. I am thinking of upgrading my Forsee ability to its final control, which allows a maneuver before combat. With the Iktochi race bonus rolling a triumph allows a free maneuver before combat as well. Is it possible to activate both of these and have 2 maneuvers before combat?

Also was looking at the combination of Forewarning (seer talent), Forsee's control that adds defensive rating, and Protects advantage bonus control which adds a base defensive bonus. If I combined all three, say 2 from Protect, +3 from Forewarning, and +2 from Forsee. The ability to use a force action as a maneuver, which is on the Seers tree, I should be able to activate Protect and Forewarning in my first turn of combat. Is this possible? I think the only one that isn't + is protect.

Also I noticed Sage has the same The Force is my Ally talent which allows once per session a force ability as a maneuver. Do these stack or have ranks to allow 2 per session?

The force is my ally is an unranked talent, once you buy it in one tree it is considered purchased in any other tree, you still have to buy down to it in other trees, but when your there just tick it without cost. All that means that you only ever benefit from it once per session.

The 2 maneuvers before combat should be fine, assuming you meet all requirements for each.
