    • Sweeping Effluvium Beam: Gathers Effluvium to sweep a fan shaped area in front of him with a continuous beam. Heavy damage, can stun.
    • Downward Effluvium Beam: Gets up on his hind legs and gathers Effluvium to shoot the beam down right at its feet. Clouds of Effluvium will disperse from the center in multiple directions, dealing moderate damage and knocking you back on contact.

    • Generally raises his attack speed and frequency.
    • The fungi on his body will shoot more spores.
    • Gains a unique attack where it hovers in the air briefly and bursts forth spore pods in every direction. The pressure from this explosion can knock the player back if they are too close to the epicenter, as well as getting hit by one of the spore pods (which can also stun the player). These spore pods will then explode, creating a thick fog in a large circle for 60s and will cause significant damage to players within it. This fog does stay fairly low to the ground, so elevating yourself (such as when mounting the monster, which causes it to fly) is one way to avoid this damage.
  • The Fungal patches on its body can be broken.
  • Effluvia Resistance 3 will prevent your health from being cut in half, also consider Nulberries if you can't fit Effluvia Resistance into your build.
  • Is immune to flash effects until the spores coating its head are broken
  • Repeatedly using the Slinger Burst to slam him into a wall will eventually result in a head break.
  • Contact with the spores will occasionally alter the appearance and behavior of some small animals, such as wingdrakes, jagras, and aptanoths.  They will appear gray/ashen and become aggressive.

      Bruh why do people think this is so hard, I just got to it at mr 19 and almost have its armor finished in one day.

        the laser beam attack doesn't flinches you and ticks for a several time in a matter of second insta carting you. on other hand you get knocked away by stupid gas clouds. is this for real?

        • Anonymous

          by far on of the most stupid fight of the game. The AI is terrible and his ability is just cheese.

          MR is a terrible mode in general, and it goes to its apex with him.

            It shouldn't be that bad if not for those cloud attacks. The goddamn hitbox. Where does it end? Where does it begin? I despise cloud-shaped attacks in any game with every fibre of my being because I CAN'T SEE THE GODDAMN HITBOX.

              Idea: set the quest for 2 people and get tons of heal power and spam it when someone gets effluvia buildup

                Pretty easy elder dragon. Took me 26 minuntes to kill him with explosion element hammer in first attempt. Get that 3x Effluvia resistance and just dodge xD, nothing special. If you progressed to that monster in Iceborne you should be more experienced and kill him without any major problems.

                • Anonymous

                  Imagine having 3x Effluvia resistance AND clearmind charm, yet still taking massive damage from his effluvia aura and effluvia clouds. Whoever coded this fight is a clown.

                    Hold up let me get this straight breaking his chest awards you wings? Okay I know it can be difficult to reach his wings if your not a Glaive or ranged main but still and very generous of capcom

                      JEBUS please read this

                      • I have done IT!!! I have slayed him. And hooo boi it was a tough fight WITH elfuivia resistance. You defenitly want that. I would recomend Acidic Glavenus head because 1 some people are already farming him due to his weapons. and most people have at least 1 miasma jewel so those two together give level 3
