Active Strategies

There are two ways to take down the Matriarchs:

Repeatedly killing a single Matriarch
Killing 3 one-after-another with a hybrid gear setup (Orikalka, Rathis and Pthentraken)

Method 1: Killing a single matriarch

Killing 1 matriarch at a time is straight forward - bring your best gear of any style and perform an ultimate rotation

General tips

⬥ While waiting for death animation, build adrenaline by either: • Targeting a nearby matriarch and using a defensive ability such as

• Using the Persistent Rage

relic

Tips for killing Orikalka

⬥ Utilise binds and channeled abilities when possible to prevent Frostbite from slowing down your kills

⬥ If you get Frostbite, use

and do not finish off Orikalka. Instead, wait until fissures spawn then stand near one to clear Frostbite

Tips for killing Rathis

⬥ Stand in melee distance of Rathis, else her melee attack turns to a charge that will stun you

Tips for killing Pthentraken

⬥ Walk along tiles closest to East wall while travelling to avoid Orikalka aggro ⬥ Avoid the lightning or wear

to heavily reduce damage taken

Tips for killing Osseous

⬥ Stand in melee distance

Example kills

⬥ Example Pthentraken kills (60kph) ⬥ Example Osseous kills

Method 2: Killing multiple matriarchs (Hybrid)

Hybridding

Killing multiple matriarchs in parallel require much higher gear and effort over killing a single one, but gives a significantly higher KPH

General tips

⬥ Alternate between a pair of matriarchs with minimal banking, doing no food kills for the entire hour. • If

is not owned, presets should be made for 30 minute combat instead of camping the entire instance. ⬩ Use 4

for such a preset. • Perked hybrid armour such as

can be taken instead, although this will reduce kph. • You can target Rathis from far and use defensives to get 100% for

Example ⬥ Feel free to come up with your own rotations based on your gear if lacking BIS. • You will likely still be able to get ~85 KPH or more even if not bridding optimally. ⬥ Use
