DPS will need to focus on the boss and let the tank kill the pods. This works best with a Death Knight or Paladin tank. You can also use a melee dps to quick kill the pods since they only have 20k health.
Kill pods the moment they bloom, it's easier than killing the flowers
Kill any pods that form into flowers
Kill the boss
The tank needs to keep an eye out for the Spore and taunt it to him where it's death will both harm the boss and create a dirty brown pool on the floor
Position the boss into the brown pool while avoiding it yourself
If the tank kills the pods quickly you will prevent the boss getting heals, dps can quickly take this boss down with only a tank and maybe one dps on the pods.
Ammunae's name is most likely based on Amun, the Egyptian god of creation and the wind, whereas his appearance is likely based on Khnum, a nile god with the head of a ram, considered to be a god of creation due to his moulding of people on a potters wheel using mud from the Nile, explaining Ammunae being the Construct of Life.
