      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.

          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.

                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

                  I did him in today with a maxed Glavenus glaive. 5 mounts and going ape**** when he drops. It was a thing of beauty. 40 minutes of intense combat, no carts.
                  Everybody takes a blast bug, but I swear by my healcloud bug

                    Went in without effluvia resistence, died in the first 3-5 mins. Got the resistence, didnt die once, easiest eldr dragon so far for me.
