The biggest threats on that fight to watch out for:

• When the main boss raises a mirror, it shields her from damage. Furthermore, doing direct damage to that mirror will cause shards to break off from that mirror, and each shard is basically a homing missile that will ram you after a few seconds. These individual shards are usually not a major issue, since they hit you one at a time. If you do enough damage to the mirror to cause it to completely shatter, it will cause 4 of these shards to spawn at once, and all 4 will fly into you all at once, and this is quite deadly since you're taking all of these hits at the same time. Your two options are to avoid doing direct damage to the boss while the mirror shield is up. Or to dodge the shards if you shatter the mirror.
• Laser beams do ramping damage the more often you are hit by it, so you really should avoid being hit by it.
• The blobs will have an interruptible ability that you need to interrupt; they're constantly shooting small nearly-invisible projectiles at you while they're channeling ("Seeking Spheres", IIRC), and the damage from this ramps up. It's not painful initially, but will grow to be lethal if left alone for too long.
• The manticora will summon something called a "Glass Ceiling", which is a big disc of broken glass hovering in the sky, and this disc of glass will follow you around (so you can't run away from it). After several seconds, this disc of glass will slam down onto the ground and will kill you. When it is about to slam down (about a second or two before it slams down), you will see a big red circular telegraph on the ground, and it will stop following you. This is your chance to react to the mechanic. You can either block it, move out of it (since it stops following you when it's preparing to slam down, so if you are quick, you can dash out of it in that brief window when it stops to prepare to slam down), or roll-dodge the damage (roll when the AoE telegraph appears).

@code65536 you're amazing, thank you! Just got one more question, in the 2nd cycle she summoned an atronach which seems to have more hp than she does, is that something we should focus on?

Each arc (up to arc 4) adds a new boss.

So in the first arc, it's just the humanoid. In the second arc, it's the humanoid and frost atronach. The atronach isn't an add; it's a boss.

Each new boss appears when the previous boss reaches a certain health threshold. The second boss appears when the first boss reaches a certain health threshold. The third boss (in arc 3) appears when the second boss reaches a certain health threshold. And so on.

This means that the safest strategy is to focus the bosses one at a time. So kill the humanoid before working on killing the atronach. If you go focus the atronach before finishing off the humanoid, then the third boss (in arc 3 and beyond) will appear and you'll be dealing with three bosses all at once, whereas if you kill them one at a time in order, you'll have at most just two bosses up at any given time.

I think this can be helpfull:

In the end there are explanations of arc final bosses and marauders.

I know I'm late to the party but thank you so damn much for this. Really helpful.
