General Knowledge:

AOE Damage is important. It reduces boss tentacles

Cleansing is important. You must have a cleanser. 

Immunity is also important. After you are cleansed immunity will keep you clean.

Pay attention to the rift enhancements. They will make certain units more viable as you progress.

Make sure to use rift pet.

Tip #1:            

Have the best units for the job. This means Bellona and Immortal Wukong for the most part. Bernard is a good healer for it. 

Sadly, I don't have the best units. I use Bernard, Vivian, and Immortal Wukong as my core group. My 4th unit is between Ram and Landy. One def breaks, the other does damage. They're about the same in terms of performance. Neither is ideal.

Tip #2: 

Don't skip rift. The more rift score you get the faster clears will get. Make sure to at least soak up the main pass rewards.

Tip #3:

Watch TristenWulf's guides on YouTube. Seriously. If you are unsure what units to use with what you have, there is no better explanation online right now than what he provides in his content.
