Second Wind II + Prime Conditioning + Seasoned Veteran is good for 520+HP on my MRD.
But when it comes to soloing and preserving your stamina bar using sacrifice II or III is the way to go.

If this thread is meant for helping you solo I would suggest LNC to 20 for Feint, PUG to 14 for Featherfoot & Jarring Strike, and using Foresight & Fracture from MRD.

Feint without a doubt is very valuable to any DoW allowing you to do WS dmg for 500TP after you miss.
The Featherfoot and Foresight combo with their corresponding reaction WSs gives a huge edge over anything you fight.
Not only do you get to evade and parry an attack taking no damage, but you also get to counter with WS dmg for only 250TP and costing you ZERO stamina.
