      I swear, I was losing my***** after 3 attempts, twice with my main weapon, the lance, once with my off-main weapon, bow. He completely *****ed me, besides the bow attempt, in which I died my third time on the literal 50th minute (I quit to not lose my wasted items). Then I put in 3 Effluvia gems into my armor, and suddenly I have no problems whatsoever with my lance. Aside from the Large Elder Dragon Gem I need, I could make two whole sets of his armor now, really recommending to try getting effluvia debuff resistance slotted if anyone has problems, might help!

        Why has none of the comments OR the page itself mentioned that when you get hit by it's Effluvium attacks, you can become a FREAKING ZOMBIE?

          Not sure if this dude's just blind and deaf cuz most of his body is rotted away, but I love how nonagressive he is. He also reminds me a lot of Chameleos

            fantastic fight for me. Its still hazak so its pretty much the usual side hugging but his new moves allows for more LS foresight slash/Iai slash opportunity. his downward breath is probably not tested enough though and need some patching. I'm pretty sure I countered it every time it happens but somehow the attack still hit my back side sometimes. needs to position myself really well before the counter to get a clean foresight slash.

              Anyone else feel like this thing had a boat load of health? First run timed out and i only got the "near death" indicator a minute before after wailing on it pretty consistently.

                It’s a ripoff vaal hazak that’s in the ancient forest so if you know it well you can use stuff like falling boulders on it
