This is to give you an idea of what to expect, describing some of the mechanics and giving a few tips - I hope I don't give too much away, as there are fun things to learn, but I wanted to provide some basics and tips for those who want to know some information. I might post a full guide later on after everyone has gotten a chance to run it with the thrill of the unknown. Please please correct me or add your own thoughts or strategies below.
Boss1 - Manor _______ (Servant? Jester? idrc)
Basic Mechanics - Single boss with many adds spawning throughout, increasing in strength and number until the boss is dead.
Basic Strategy - Tank needs to get the attention of everything, DPS needs to kill the adds, healer needs to heal everyone (pretty basic!!)
Tip: There will be AE circles that stick on the ground throughout the fight which the party needs to avoid. I would recommend that you stick very close to the healer, and Flash/Overpower the adds as they come to attack the healer instead of chasing them around.
Boss2 - Ash
Basic Mechanics - Ash hits fairly hard, looks awesome, and has some pretty cool magical/telepathic powers with his glowing axes and swords. The biggest part of this fight is his floor AEs, he will throw down a multitude of different damage dealing floor AEs that should be avoided.
Basic Strategy - Dodge dodge dodge. Stay light on your feet, try not to move the boss a TON, as it will piss off your dps, and be cognizant of where your healer is relative to you.
Tips: Always be moving a little bit, its so easy to react and move if you are pacing or walking the boss as opposed to being flat footed (just mentally, not any game mechanic that I know of, besides acceleration to full speed). I THINK there are some ground AEs.
Boss3 - Crazy Succubus Lady (Halleklsgfefdfjlk)
Basic Mechanics - This lady does some strong magic attacks (Void Thunder/Fire IV) Void Fire IV will target a random party member and its a wide AE. She can be stunned/silence, but does gain resistance, I would save those for her brutal Dark Mists which have a large range and a relatively short cast time. It seems that YOU CANNOT run behind her to avoid spell damage! DOH! They caught on!
Anyways, the main crux of this fight is the adds. Add 1 is a Manor Servant (eyeball), Add set 2 is two Maidservants (succubi), and add 3 is...I dunno a gargoyle? I don't remember. If your group does not dps them down to 0 or very little hp by the time she chooses to sacrifice them (not very long) she does a very powerful Blood Rain (or something) AE on the party. It wiped my group one time. She does not seem to absorb on proximity, but I tried to keep my body between her and the adds, as it seemed she absorbed the last add VERY fast. This is entirely a DPS check fight. Other than killing the mobs fast, its not difficult.
Well - that's all the boss fights in Haukke - it was a super fun dungeon for me. It drops i60 armor, 100 philo, and 50 myth
