Not live yet, just want to make sure the new naming pattern gets used. Stack up every buff in the game and make his HP 0 before yours, is the strat.
Immediate use of Lightning Armor - Possible to remove with JA/Blue Spells but resists dispel/finale. Uses Stunga (enmity reset)/Bolt Strike/Chaotic Strike/Thunder Spark (single target) every 20 seconds regardless of TP. Will use Astral Conduit Bolt Strike spam (another enmity change on use)
After Ramuh a SMN Doppleganger will spawn and call elemental avatars. Uses Alexander or Odin @ around 50% (ANOTHER enmity swap)
VE/E Kill ramuh, kill whichever avatar spawns, kill Doppleganger. Pretty straight forward.
N Kill Ramuh, Kill whichever avatar spawns, then sleep/grav doppleganger and kill immediately or wait for 2 additional elemental avatars.
D/VD same, but more elemental avatars. 21k HP give or take on the doppleganger, 2 QD around 10k each to kill.
Alex/Odin can be killed, if you're capable, low HP, but some risk. Can be run from as well.
