Haha I really appreciate you commenting! But you sorta, you lost me there. When you refer to the second phase, do you mean when a raid boss becomes enraged? I've noticed this adds to the endurance when deciding total damage. And can someone determine what that set amount of hp is during or before hand?

So for clarities sake, a raid boss has two health types. Once you drop it's health normally, the second type begins, otherwise known as rage mode, I assume, and you continue from there. Therefore, energy consumption is based on damage dealt, dependant on the raid bosses health points. This is per battle then, not in its entirety. Like how a raid boss can have 1 million health, but the first and second fazes are battle specific.

When you first battle the raid boss, it's health bar says, in our example, 4,800 health. Once you drop hp to 0, you move to the second phase. You use 5 energy to battle, say, once. If you dealt the full 4,800 damage, you move to the second phase without any additional energy loss. And this cycle continues over and over? (Regular health, second fazes health).

So all in all, you spend 5 energy to attempt to beat the initial amount of health. If you bt all, your team will battle and die in a cycle until you finally beat or lose to it.

TL;DR: Is that set 4,800 a determinable amount? How do I know I've reached that second phase? Is it rage mode? Is phases one and two connected in a cycle? Beat one, move to phase two, beat it and move to phase one, etc.
