Actually, yes it does seem to get affected by EM:

Now... I can't see anyone surviving 4x Shock + 4x Fire nova + 4x Crit TS. Looks like roughly 20-25k damage to me.. and good news is that the TS is an aoe spell so it won't be grounded or spell reflected.


Basically as far as I can tell, we have a guaranteed kill on anyone that comes close.
