Here you will want to play as a dps character to kill the bosses as fast as possible. My personal dps of choice here is Hermit, but anything can work.

Hint 1: I recommend building this pylon as the last part of your build and upgrading it to either 1 or 3 stars to increase the range of your aurastacks and traps as much as possible.

Stats are what i believe you will require to run all of Crystalline dimension on ruthless without getting a massive headache. More stats > Less headache.

Now good luck fighting this version of The Old One :) I have a few recommendations for DPS heroes here depending on how comfortable you are with the fight.
- Do not forget to join with 3 additional splits if this is intended for farming (1 weapon drop per split).

The Old One:

DPS Hermit: Propeller cat pet, specced in hdmg or hhp with 2.5k+ ab1 and ab2, relies on hitting both feet with Thorn Shot (AB1) to increase efficiency. When Old One slams his fists you can also use your right click ability to hit both hands, further decreasing the kill time for each phase. Make sure to use Thorn Shot as often as possible as the tick damage really adds up quickly.

DPS Monk: Lover's Cupid pet, specced in hhp, hdmg or ab2. This is the safer option, as the Lover's Cupid will keep you topped up on health and can help you clear despite making a few mistakes throughout the fight. It is however much, much slower than a Hermit.

When you get very comfortable with the fight, you can play Hermit on your main split, and manage a second split with a monk specced in full ab2 to actively Hero Boost your hermit. This will cut the time to kill in half.
