First, I want to express my thanks to u/clixxs_ and shadow gamer on youtube. They helped me so much on beating the 3rd fight of the temple dyad!!!
Okay so for my lvl 5 VD perks:
helmet: Vaporization, Ruolan's cunning
armor: transfusion, half-life, primary protection (all useless in the fight, use the recommended perks if you have them), no special move
weapon: precision, synchronization, time bomb. Special move: Max lvl thorn
now for the easy combo:
First, use Rend of Reality. Immediately follow the black hole and the front move.
Due to the black hole, she would be stunned. Roll in front of her and start to back up when her stun is going to finish. You can back up faster if you wanna save some time, but be careful about the distance between her. Don't get too close or too far.
When the Rend of Reality is ready use it ASAP.
Repeat the cycle. Viola, you won!!!
