High range build
Many players prefer a smaller bubble... downside is, that also comes with a reduced Avalanche range.
This build is primarily meant to keep you, your squad mates and your defense target (or whatever you want to [Protect]) safe and healthy. But it does a very good job on "mobile" missions (e.g. Rescue, Exterminate, ...) aswell.
Use Avalanche (4) to your heart's content, keeping enemies frozen while adding that extra layer of defense via [Icy Avalanche] (Augment mod).
Feel free to experiment, try different Augments or improve this build with Umbral mods...anything goes.
Arcanes are optional. I recommend Grace, Guardian, Barrier, and/or Aegis for extra tankiness, Energize for better energy sustain, or whatever else you prefer/own...
10.2sec freeze duration
There's always some more potential to further minmax, but I like this build and its moderate amount of polarized slots, leaving room for variations and alternative configs.
