This seems counter-intuitive, but use a Decaying Dragon Key with this build to increase survivability in high damage situations where the base 450 shields will be instantly shredded. When using a Decaying Dragon Key, casting Discharge or Electric Shield fully refreshes the shield gate because of the aura [Brief Respite] (a fully refreshed shield gate gives 1.3 seconds of invulnerability as opposed to the .33 seconds of invulnerability of a partially refreshed shield gate).

I use this build for fun, serviceable and survivable in high level missions. This build works more than fine with regular [Vitality] and [Intensify] if you don't feel like using the Umbral versions. Plenty of speed for yourself, use either Arcane Energize or Exodia Brave to sustain your energy.

The use of [Shock Trooper] allows for additional flexibility on your weapon builds, allowing you to only put a toxin elemental on your weapons instead of the usual full corrosive combo. Also turns your sentinel into a crowd control machine.

[Natural Talent] allows you to quickly place down shields in order to boost weapon critical damage.

A unique form of CC this build has is in [Aero Vantage]. Jump, aim glide, then cast Shock and land. This puts multiple enemies to sleep. If you don't make use of this, swap it out for either [Rush] or [Streamlined Form].

Discharge is usable with this build, but it usually only serves as CC.
