Durendil has posted videos and strategies for hunter soloing the bosses in heroic Scarlet Monastery:
Thalnos the Soulrender
Durendil:A non-trivial boss, he has many abilities that must be dealt with.
His spirit gale will deal 40K damage and spawn a void zone. You can avoid the 40K either by being far away and moving, or by interrupting him.
He will spawn little adds. They stack quickly a nasty debuff, so aoe them quickly. I personally used survival spec in this fight to deal with those. He also spawns other little adds with sever soul, they are mostly harmless.
Finally, big adds. They melee hard, so trap one at all times to reduce damage on pet.
Durendil: 1, 2, 1 – 2 -3 – 4:
Don’t staaaaaaand in the fiiiiiire.
Easiest boss ever.
High Inquisitor Whitemane
Durendil: Your pet will take a lot of damage in this fight, so you may want to use a stamina trinket.
Phase 1 is a simple tank and spank.
Phase 2 also. Just remember to interrupt her resurrection.
You want to keep your CDs for phase 3. Quickly burst Whitemane and the hardest part is done.
