What is strategy to beat OM?

I heard you need high lv ark. obviously.

All shadow arks.  Shadowlance and glowing dino. and shadow ocrina.

I tried with 3 shadowance and 2 glowing dino and I can’t reach far… do you guys also have healers and support? how many healers and support… and my healers die after healing… … is there any other ark that i can heal and they wont scarifies themselves?

also how many dino and shadow should i make?

The healers only heal when your shadow arks are at low hp.Angelon,and Halopard are popular healers.The reason youre not getting far is because you need like 4 shadowlances and 8 plasmorexes…
Level them all to 99,and your good to go!

Nilomoth and guardiron have risky heal which would come in handy

Also, DO NOT!!! Use the shadow method on dungeons with holy arks or holy bosses. You will get rekt.
