This build is meant for shorter missions and is meant to focus on [Caliban]'s 4th ability. You go in, get your shields up, and you "flash fry" enemies to be armor stripped with your 4.
The build is meant to have several survivability "checks".
You can replace [Energy Siphon] with [Brief Respite] and quickly rebuild your shields with your conculysts. [Rolling Guard] also lets you cast Condemn and get more shields quickly.
My Archon Shards are extra energy efficiency, faster casting speed, more shields, more energy, and more strength.
