The easy way to taking down the Succubus easily is to know when she reveals the weak (red) spot on her forehead. Take note of all the attacks where she reveals it and optimize your chances. =)

She has a total of 3 health bars, and each time you take one down there'll be a short cutscene. After the cutscene, demon pull the cables. If you can't reach it, move over to the next platform.

Claw swipe:
You can easily see this coming. Jump/Evade to avoid. She will reveal the weak spot after this.

Single-fist Pound:
She'll slam a fist at you when you're too close for too long. You can easily evade it. Just keep your eyes open. She will reveal the weak spot after this.

Double-fist Pound:
She'll raise both her fists and pound it against the center of the platform. Evade/angel evade/demon evade will avoid it just fine but I recommend demon evade for the extra damage. She will reveal the weak spot after this.

Ground spikes:
Spikes will emerge from the ground and trail after you. Run away from the trail to avoid. Unless she's stunned, try to keep your combos short so that you can 'cancel' your attacks in case she does this and you need to start running.

Scream:
Succubus does this to knock you away. It cannot be evaded but can be avoided by keeping your distance from her from time to time.

Bile Attack:
Succubus pukes corrosive bile all over the platform. This means it's time for you to move on to the next platform quickly.
