Strategy for act 3 boss? (spoilers ofc)

Two words : Rejuvenation Totem.
I died 2 times i guess before defeating this boss. The time to see what can i do or not.

Marauder ~35, 800 hp, res 75% cold/70% fire/53% lightning. With Hatred aura, sometimes Molten Shell. But with a good placement of the totem then heavy strike spam, it's okay.

None of the bosses deal chaos damage so you can faceroll them all through merciless on marauder atleast, the problem is mobs who deal chaos.

I've soloed her in normal and cruel and posted both videos on my channel. Cruel was easier (despite a lag spike and a stupid death) since I had totems and skeletons to take heat off of me. Normal I was learning the fight.

Best I found out, choose 1 element type and unload on her in that form. Make sure your resist is maxed for that type. I chose lightning. So for cold I hid behind a pillar. For fire I kept moving (again this was normal difficulty). The only thing I had to avoid for lightning was the ball lightning. If possible hit her once or twice to keep ES from recharging. And when in doubt bring plenty of portal scrolls. You can either portal for recharged potions. Or just quick travel after a death (unless you are HC).

And being a few levels above the zone doesn't hurt. Fellshrine is a good place to grind for a bit in A2. Chances are that if you grind out enough there you will still be a couple levels above the zone by the time you hit the end of A3.

If you have any kind of summons (totems, skeletons, zombies, etc) spread them out whenever possible. Oh and for me I had double curse which helped a ton. They were permanent so no having to reapply.

Since many builds don't come into their own until about level 40-50, running in a party is fine. I only went solo so I could fraps solo kills. If you are in HC, unless you are sure you are fine (and are sure the servers are stable at the time), just go for the group.

puncture when she is in human form
puncture and run around when she is in fire form
run away behind pillar from ice form,

on merc I kill here like this (with my CI fire caster):
spam fireball when she is in human form
molten shell + life leech (CI+vaal pact+ghost reaver) when she is in fire form and just stand there for here to hit me.
run away behind pillar from ice projectiles.

Kill blue circles and the fight is really easy as solo. If she do managed to go into a blue circle hide behind one of the pillars
