Hunter solo - Durendil vs Aberrus Heroic
Done with 613 ilvl. I still overgeared the fights, but unlike Vault I actually had to follow the strategy on some bosses.
The hardest was Magmorax, since you die at 25 stacks. This means you have to soak one of the circles, soak the pool near the boss, and then don't soak the pool on you - put it on the side.
The first pools are the hardest - you need to soak the circle + pool then run to the edge, all while moving very fast.
If I managed well the pool, I could manage the dps check, but with 10 less ilvls it could have been very tight.
On Rashok, his tank buster ability still hits very hard. So I had to reuse the strategy where I misdirect on my second pet.
Also, his energy goes up faster compared to normal, so I had to get him to the middle after the second soak.
Lastly, Sarkareth. As in normal, I had to delay pushing him to phase 2 until after the stacks from the bombs faded in order to avoid a restack.
For the other bosses, I could do "easy" strategies through sheer dps (ex : no traps on Zskarn).
