MODS
If you don't have an Umbra Forma, use [Vitality] instead.
And if you prefer a bit more energy gains then you can swap [Equilibrium] with either [Augur Message] or Stretch, depending if you don't mind dropping range or duration.
ARCHON SHARDS
The ones I'm using are as follows:
Two Amber Archon Shards -> 50% casting speed
Two Azure Archon Shards -> +100 Energy Max.
One Tauforged Amber Archon Shard -> +75% Effectiveness on Energy Orbs
I'd argue that the two Amber Archon Shards are interchangeable depending on if you'd prefer more toxin damage for her 4, or something else.
RECOMMENDED COMPANION: [Nautilus Prime]
[Oraxia] is constantly using energy when her 4 is active, which makes [Nautilus] the perfect companion due to taking advantage of Summoner's Wrath and [Duplex Bond]. Additionally, [Cordon] will group up enemies and make it easier to apply [Oraxia]'s 3 (Widow's Brood) so she can spawn her Scuttlers, which also take advantage of Summoner's Wrath.

For his weapon, I recommend the [Verglas Prime].
