Build for defending points like the stations in Mobile Defense.
Minimum range to minimize area that is vulnerable to Nullifiers.
With clever use of [Rolling Guard] you can be essentially invincible(never exposed to damage, but ofc not active constantly).
For convenience during lazier play you could run [Quick Thinking] for a massive amount of durability (744×2.4 = +1786HP) with the downside of being staggered when taking damage to Energy. Combine it with Primed Feed([Sure Footed]) to remove the stagger.
