[Protea]'s passive gives her the ability to abuse several different aspects of her kit along with subsumed buffs to make her a formidable weapons platform. Any of the buffs work but we'll focus on the best offensive and defensive ones.

Elemental Ward and Warcry give you hybrid offensive/defensive options but are a bit weaker overall. Element buffs like Nourish, Smite and Shock allow you greater freedom in your weapon loadouts but may require augments or build tweaks on those weapons. Roar, Eclipse, and [Xata]'s Whisper give you the strongest damage buffs but have certain drawbacks due to balancing decisions limiting their output.

Roar is chosen because it's the strongest option in general content out of the options listed. Nourish and Eclipse also work but require a few builds changes on your weapons.

[Blaze] Artillery is replaced because it's too weak on this build and competes with Grenade Fan for APM. You should only run one or the other now that the subsume system allows you to make either ability obsolete.

Shields from Grenade Fan should keep you alive in most scenarios. Most of your combat will be spent in the Temporal Anchor so the worst case scenario you'll be rewound to a safer position.

Buff abilities and Dispensary should be cast when your passive or other ability strength buffs are active. Time them accordingly as it's the only micromanagement you have to worry about in the build.

[Equilibrium] now synergizes with the boosted health orb from Dispensary to give you over a hundred energy back per orb.

Arcane Aegis protects you if it procs while you're in Temporal Anchor. It can be replaced with any other arcane to suit your playstyle.
