And I've cleared Aberrus normal ! Rashok was the hardest boss by far. This is due to the fact he is a dps race, but also deals a lot of damage, kills your pet all the time, has shorter phases since he gains 20 energy per P1. Which is "not good" for dps.
The safest strat is to get him to the middle before 100 energy. But I didn't have enough dps for that, so I had to wait for the jump the first and second time.
For the third P1 he casted his wipe before the jump.
The issue is that it's RNG if he goes into phase 2 or he casts his wipe mechanic. But the reward - more time on the boss and good CD timing next P1 - gives a big damage boost.
For the pet, I tired to misdirect on my secondary pet as much as I could.
I used a defensive trinket for the soaks.
