Maintain Elemental Blockade, Liquid Lightning, Critical Surge and Boundless Storm at all times to maintain the build’s maximum offensive/defensive potential.
Maintain Elemental Drain on your primary target to ensure you’re dealing maximum damage and getting the benefits of minor magickasteal for sustain!
In between DoT/buff applications, use Light Attack > Force Pulse. When Crystal Fragements procs, use that instead of Force Pulse!
If you are in a big AoE situation, Elemental Rage is going to be your ultimate of choice. In single target fights, use the Atronach instead!
If you know a boss/mob is going to deal a big amount of damage, use your Hardened Ward to defend yourself. Also, if you take a huge spike of damage, use your Matriarch’s ability to give yourself a nice burst heal!
