The goal of this build is to have a comfortable time in defense missions with a minimum amount of effort put into energy [Regen] and survivability.
Comfort range: Tested until 145 SP
MODS
[Dreamer's Bond]: When combined with Zenurik School and Arcane Energize it pretty much eliminates the need for [Equilibrium] however if you are having a problem with Shield Gating (Considering you are constantly using your 4th to gain Overguard this shouldn't happen) you can always go for [Brief Respite].
[Primed Sure Footed]: The OG mod that we all use but it is not necessary you can always have 1 less Forma or go for [Preparation] for an easier time starting the mission.
Augur Mods: Helps with Shield Gating also good stats.
[Rolling Guard]: For getting rid of Toxin.
[Icy Avalanche]: The core of this build and the reason you should be constantly using your 4th.
Others: Purely needed stats overall.
Arcanes
For comfort, Arcane Energize is recommended. Molt Augmented is only useful because it makes your bubble more powerful but no matter what you will have to recast it occasionally.
Helminth
Nourish for Energy Regen and Damage, Roar for Damage (Just use Eclipse), Eclipse(Tap: Damage Reduction / Hold: Damage Increase) for Damage and Survivability, Breach Surge for DOPAMINE RED CRITS
Gameplay
Never use your 1st. It needs rework, useless ability.
Put down your Bubble (3rd) and stay in it, cast 4th when enemies swarm you, cast 2nd whenever you need. Do 5-1-5 often to keep your Zenurik buff up.
