Hate Leads to Suffering

Fear leads to anger. Anger leads to hate. Hate leads to suffering... I sense much fear in you.

Just play this boss as usual but do a strict damage stop at 10% health (or even lower, but needs a lot of discipline in the group) and wait for every group member to get his hatebar to 100%, then finish the boss.

Additional Notes:

• A full hatebar leads to this debuff: [spell=107087] ( with +20% physical damage, -25% healing done, -90% hit)
• 
  
• You can use meditate to reset your hatebar, but DO NOT meditate, after everyone has a full bar and you are bringing him down.
• 
  
• It can take some time, till the boss dies due to the low hit. Bufffood and Elixiers can dampen this disadvantage.

Even though this may be bit late in expansion for something like this to be found there is actually 90% hit buff obtainable inside shado-pan monastery tricky part is getting to it. Buff is [spell=126156] and is located at coords (46, 65) on top of hill with graveyards making this achievement just reduced healing asuming whole group can get to plateu with unseen force that grants the buff. Myself I got on top using warlock with engineering jumping with Flexweave underlay with speed from nitro boosts and burning rush Behind trash pack that is most of time skipped before first bridge after Sha of Violence boss.

Edit: Made some jumping around and found spot where you can goblin glider to hill. After Sha of Violence kill 2 trash mobs that are right after and hop on top of tiger statue to the right using lantern at top of stairs and chain linked to it as stepping stones and Glider to direction that statue is watching, turning slightly before clickable corpse of trash pack to hill with many tiger statues on right. Getting timing to turn may need some fine tuning.

Edited some details in and corrected mistypes
