Raidleader Weekly: Energy and Overload on The Stone Guard

After our first night on Stone Guard it is clear that several people, are still not crystal clear on exactly how the energy/overload mechanic work and how the tanks are supposed to deal with it. I'll therefore take this Raidleader weekly and try to explain it in clear detail. There will be a lot of pictures in this post and I appologise in advance for my dreadful MS Paint skills.

First a few facts

• A Guardian gains energy whenever it stands within 12 yards of at least one of it's companion Guardians.
• Gained energy will not decay over time.
• Upon reaching 100 energy, a Guardian will cast Overload, dealing 200k+ raid damage, resetting it's energy to zero, and interrupting Pertrification if it's currently casting it.
• The same Guardian cannot cast Petrification twice in a row.

And now for the actual mechanic

Lets take a look at the setup right after a pull:

 

Two tanks (black diamonds), one holding two Guards (colored circles) and one holding one. Initially, all three are at zero energy. After the pull, one Guard will begin to cast petrification - we'll mark this one with a star - and the two next to each other will begin to gain energy - marked by a right-pointing arrow on the energy bar:

This state will be held until both Guards on the right side is at 50 energy. At this point, the tanks swap the two non-petrifying Guards (Cobalt and Amethyst in this case):

 

Now, the Cobalt Guard at 50 energy is alone and stop gain energy, whilst the Amethyst at zero energy is now together with the petrifying Jasper and will start to gain energy. This state will be held until the Jasper Guard reaches 100 energy and overloads, thus interupting Petrification and resetting it's energy. At the same time, the Amethyst Guard should now be at 50 energy:

Because the raid takes 90% reduced magic damage from the currently petrifying Guard, the 225k overload blast, should hit for a mere 22k, which is much more manageable. Hence, it is crucial that only the currently petrifying Guard ever overloads. 

Now, one of two things can happen: Either the Amethyst Guard starts to Petrify, which is trivial: The tanks will just hold the positions until the next overload. Or the Cobalt Guard will start to petrify, which require a quick response from the tanks: They should immidiately swap the Cobalt and the Amethyst:

 

In general: Whenever the lone Guard start to Petrify, the tanks swap that and that of the other two that has the highest energy. This, I think was one of the crucial points that didn't work out too well during Sunday's raid.
