NEED MORE INFO

De'manti Sheda

FYI:
AOE:
Strat: Tank and spank.

Doubt, Misery, and Depression

FYI: Cure intensive fight with a nasty dot.
AOE:
Strat: Tank and spank. I just AOE them down.

Deception

FYI:
AOE:
Strat: Tank and spank. Will summon adds, but they are really weak.

The Imp Trickster

FYI:
AOE:
Strat: Tank and spank. He dies and splits into adds, when the adds die he goes back to himself. Just burn everything.

Narmek Barreka

FYI:
AOE:
Strat: Seems like a tank and spank. May depend on what you choose. I did chest/weapons and it was nothing special. When he gets to 15% he sheds his armor and they become adds. At this point he is immune to damage until all of the adds are killed. The adds can hit like trucks so mezz as many as you can. Some are immune to mezz.

Vhal Sera (Quest Mob)

FYI: Stoneskins throughout the fight.
AOE:
Strat: DPS named to 66%. He'll summon a lightning rod onto one of the group members and stoneskin himself. Position yourselves so that he is the closest thing to the rod when it's trap triggers. You'll have ~10 secs to dps him before you'll need to repeat the process. Around 30% he'll port you up top where there are 4 cubby holes with a pillar in them. As you approach one of the pillars it will be come killable and start to heal the named. Burn it down as quickly as possible. Switch back to the named and finish the fight.

Ach'erin

FYI: Immune while his adds are up. When adds die they will spawn 5-6 ^ goos, which will memwipe every 5-10 seconds. Everything is mezzable. it's very very important you cure in the fight when the goos pop, otherwise Ach'erin will say something about his meal being marked and then port to whomever has the nox detrimental on them, and do ~500k damage.
AOE:
Strat: Tank and spank alternating between adds and named.

High Priest Mohnt and Drizzina the Lulled

FYI: Everything is mezz'able in the encounter, including the hammers. This can cut down on the incoming damage massively, if you've got a good enchanter. Note, the hammers depop, so need to be remezz'd on a regular basis.
AOE:
Strat: Separate out your toons a bit. Two different adds will spawn. Axes (unkillable that poof after a while) and some maids or something. Kill the maids off then back on Mohnt. When Drizzina spawns, get aggro but don't burn her down. Finish off Mohnt, then work on Drizzina. She spawns adds, kill them then back onto her (or you'll get overwhelmed). The adds that initially come in are "a member of the congregation", who were non-attackable NPC's until then. Once the waves are done Drizzina spawns, with two buffs up. One heals her constantly(~60k HPS) and the other increases her DPS significantly. Her movement speed is ~30%, so you can either kite her or just keep her mez'd while you finish off Priest. Once down, move to the children and /dance on one of your characters, at which point her healing buff will then be removed. You can then either move do the choir and use another emote there to get rid of the DPS buff or just kite/range her. At ~20% first the children will add and then shortly afterwards the choir.

Cara Omica (Quest Mob)

FYI: Run up to her to activate the encounter and quickly run away.
AOE: Curable focus damage 5k-16k elemental AE with 50% casting speed reduction, single target ~17k every 3 seconds uncurable arcane.
Strat: Kill the 4 specs that spawn. She'll summon a single player while you're killing the specs occasionally, but the bots moved out fast enough that she didn't get any hits in. Once they're dead, run up to her platform and it's a tank and spank.

Manifestation of Tserrina's Rage (Quest Mob)

FYI: Ghastly Curse - Cast on 2 people, if not cured it will uncurable fear. Can be interrupted.
AOE:
Strat: Kill bride's maids then kill namer. Other adds will be called while the bride's maids are up. Bride's maids will be resurrected once.
