interesting aspects of the log:
[22:51:44.773] Kaljurei Fiery Attack Warlord Zon'ozz *22442*
[22:51:44.798] Kaljurei summons Tentacle of the Old Ones with Summon Tentacle of the Old Ones
So 4 piece can summon them.
[22:08:09.140] Kaljurei Opportunity Strike Yor'sahj the Unsleeping 7811
[22:08:09.218] Kaljurei Deep Wounds Yor'sahj the Unsleeping 2446
[22:08:09.546] Kaljurei summons Tentacle of the Old Ones with Summon Tentacle of the Old Ones
Opportunity Strike can also make them proc.
He also summons 4 while using bladestorm at Yorshaj.
[22:18:09.790] Kaljurei Heroic Strike Morchok 12678
[22:18:09.830] Kaljurei Rend Morchok 4069
[22:18:10.180] Kaljurei summons Tentacle of the Old Ones with Summon Tentacle of the Old Ones
Rend MIGHT have procced the tentacle on Morchok. And it is confirmed off the Hagara log:
[22:23:24.781] Kaljurei Rend Bound Lightning Elemental 3038
[22:23:25.187] Kaljurei summons Tentacle of the Old Ones with Summon Tentacle of the Old Ones
I particularly like the fact that rend can procc it. Thank you for the log sir.
Edit: ill leave the 4 piece statement as unsure. From what i saw on the logs the tentacle was proccing off an attack made 0.4 seconds before it spawned. So it would seem it was not the Fiery Attack but the Mortal Strike that procced it. Either way its some good solid data
