This puzzle is like the tower of hanoi in that you cant place a larger number on top a smaller one. The idea is that in order to fire, you must first move each symbol to the 3rd slot and have them in a tower shape. This will allow them to shoot the boss. below is a quick little idea of what exactly that looks like. I took each slot and just used a number to indicate the symbol in that slot based on the amount of prongs.

1|2|3

1|0|2,3

0|0|1,2,3 fire

0|1|2,3

2|1|3

1,2|0|3

1,2|3|0

2|3|1

0|2,3|1

0|1,2,3|0 fire

0|2,3|1

2|3|1

1,2|3|0

1,2|0|3

2|1|3

0|1|2,3

0|0|1,2,3 fire

Repeat by just moving the boss from the first cannon to the 2nd. You can fire off of these 2 since you dont have to fire all three to gain access to previous fired cannons.

In terms of the buttons you must push it looks like this. 2-3, 1-3, fire, 3-2, 3-1, 2-1, 3-2, 1-3, 1-2, 3-2, fire etc. Hope this helps people do it faster. Due to the armor debuff the tank receives, It is easier to swap tanks out between each firing than to try to keep one up through out the entire fight. Other than that, the fight is a simple tank and spank.

Tower of Hanoi

Look it up and all shall become clear!

If your tank is good at positioning he shouldn't receive the debuff at all. We had two ranged dps up top working the consoles. I being one of them would call out whatever spot was going to be ready to drop the lava.

The tank would then position the mob between the two black lines and have himself outside the caution lines. He would then call ready and we would drop the lava.

You can also ignore most of the stun mines up top as they don't really interfere with using the consoles (except for one on the right side).
