Spoilers: HoH Boss mechanics

General Notes:
- Magicite 1 shots any floor, so far we saw: Garuda, Ifrit, Titan, Odin (It seems that Odin can 1 shot bosses???)
- Magicite does 10%-25% of a bosses HP (depending on what floor) but do not use it to pull, as the boss will instantly reset
- Petrification makes all enemies stone, 1 hit will kill them so clear fast.  Traps will still be active and will spawn non-stoned enemies
- Fragility? (whatever the enfeeblement pomander is called) works on bosses, heavily advised if going in under geared


Floor 10: Funa Yurei (A rank in Ruby Sea) sucks you in then does a cleave on half the arena, very simple
Floor 20: The moth from that one dungeon, does an eye attack, and then the butterflies around the edge of the arena explode (this will 1 shot you probably), does some other things but the only really dangerous thing is the butterflies
Floor 30: Get knocked up by the boss into a cloud to not get a vuln up
Floor 40: Green Blob thing, does aero knock back, make sure you dont get knocked into the aero currents on the edge
Floor 50: chimera thing?  Looks in a direction = big laser, cleaves, does a proximity aoe and spawns pulsing orbs that kill, orbs pulse 3? times
Floor 60: Scylla, rods make donut aoe's and line aoe's, just dont stand in aoe's
Floor 70: stand in the puddle if you get targeted by hound out of hell, and ONLY when you get targeted by hound out of hell. insta death if you are in it for any other attack or out of it for hound out of hell
Floor 80: “fenrir (didn't see the real name). There's almost no mechanics on the guy, he does a cleave, random target damage (at ~65 aetherpool it did around 6.5k damage), then spawns ice blocks around arena, drops icicle and it flies through blocks exploding them. If you get into such blast (AoE is pretty huge around the block), you'll get frozen and possibly killed by next raid-wide. After that he starts again.” Thanks /u/Bisu_Briareus
Floor 90: "Xande reskin. He spawns tons of balls that explode one by one. They have a large aoe so it's easy to get clipped by them if youre semi close. He also does a meteor distance aoe you have to get away from, and a linear attack. All 3 overlap at once.  Besides that it's basic circle aoes. Knuckle press and burning rave." Thanks /u/Nauvio

Good luck to everyone!  Conquer the tower :)
