This new website for the game's relaunch is still incomplete. In the meantime, most of the old guides on the legacy website should still prove useful. Most missions have not changed.Legacy website
Haugbui Jarl: Deep Calling can be LoS'd by walking behind him after he
starts the cast as Ledoke stated. Charged Hack can be ranged by dodging
away from him right before the cast ends. In E5 he gets another skill
called Mjolnir's Echo; this must be impaired.
Blarbane Sorceress: Tide Wall cannot be impaired as Killswitch stated. It can and should be purged, however.
Varangian: Again Charged Hack can be ranged or impaired. Again in E5
he gains a new skill called Mjolnir's Echo that must be impaired. The
"hiding" spot is no longer a ridiculously obvious white particle
effect. It is a small ripple in the water that is actually somewhat
difficult to distinguish.
Haugbui Mother: Small detail, but the
adds are called Volatile Hosts. In E5 and above the Sea Horrors have an
insane evade buff that will have to be bypassed with GtAoE or purged.
Dweller: Volatile Hosts* Also Synapse Spasm can, and should be
impaired. It does a crazy amount of damage. Tide Wall cannot be
impaired, but it can and should be purged.
Ur-Draug: He cleaves
in all difficulties above story mode as stated by GreyRaven. In E5 and
above the "bubbles" in phase C will also root players in place.
Someone must have a full party cleanse to avoid a wipe.
Great guides in general!!
I'm having difficulties to get beyond Beaumont (Tier 21) though. It is not something of the special abilities, but his common DPS that seems to neck me (I manage to kill his clones fast and the dogs within a reasonable time). First I tried at level 30, then decided to go level up before trying again. So, here I am, stats improved, even have a couple of blue items equipped, but it doesn't matter much. I can hold out a bit longer, but he kills me after I killed the dogs. I suppose my build might be sub par, but compared to normal leveling, gather the AP and SP goed very slowly (and through some weird issue in Steam I can only spend €5 at max per day, so I can't even very well pay to win,lol).
I don't notice any healing effects of the Gaia engine. I also wonder whether the buff from the holy water remains active (I died a few times meanwhile).
So, I'm curious to other people's experiences in this particular fight. I hope I eventually manage, otherwise I won't even see the Secret World beyond Solomon Islands, Agartha and the capitols.
EDIT I reworked my build, ensuring I got a self-heal; that allowed me to finish this quest. The part about the Gaia-engine healing you in the guide, seems to be outdated so yoy have to heal yourself.
