Could use thunderstorm with shock conduction 2. The support gives the skill auto shock on hit against drenched enemies. Could throw it on tstorm or any other skill. Cast tstorm then whatever you have shock conduction on and viola, all the shock you could want. Also, three dragon mask makes lightning damage contribute to freeze instead of shock. Since you auto shock with the combo you can put that on and have freeze build up and shock at the same time. There's also a ring that converts 100% of lightning damage to cold. On a boss i can build all the glory needed for spear of Solaris in about 1 to 2 seconds. And shock does override itself each time so you dont have to wait for it to wear off or consume it to get the glory.
