|With high base Def and Res, Sheena is already equipped to handle most incoming attacks. The most effective use of this build is to use Sheena as a mobile barrier accompanied by dive units such as Kagero and Hinoka (WF). The Carrot Axe+ with the Res bonus creates an equilibrium in Sheena's defenses, making most attacks against her fairly unimpressive even when boosted. Combining Noontime with Carrot Axe+ and Renewal 3 allows Sheena to get a steady influx of health, allowing for the healer to focus on other units or to negate the need for a healer at all.
Brazen Def/Res 3 is an expensive ability to acquire, but this allows Sheena's health to fluctuate in a more controllable fashion and ensures that when her health is low she will likely be able to recover.
Atk Smoke 3 is a good ability to use with Sheena as further defensive reassurance. Attacking a foe and setting this debuff in action is a fairly decent alternative to Distant Def 3, if used effectively. This allows Sheena to have the Armored Boots seal, doubling her movement.
Armored Boots is useful here in positioning, as Armored Boots allows Sheena to navigate difficult terrain (such as trees) faster than infantry units. Equipping Sheena with Reposition allows for Sheena to navigate difficult terrain and effectively throw allies over it, making assassinations more manageable for glass cannon units.
Noontime, while it allows for survival, is not an impressive move when dealing damage, but the small numbers combined with Carrot Axe+ further allow for Sheena to take a heavy beating and come out alive. Replacing this with Aether is a risky but efficient choice, as the steady health won't be present, though the heavy damage and health return may make it worth the patience in some cases.
