Insect Glaive build if you haven't beaten Fatalis - Monster Hunter World: Iceborne

I would like to share two Insect Glaive builds created by Vandelous (his discord: Vandelous#3141). They are aimed specifically for Fatalis and should help you immensely in the fight

The first one is concentrated more for support:

At the start of the hunt put on the Ghilie Mantle to get on the canons and fill them with cannon balls. The maintenance Jewels will allow the mantle to reset faster. When the cannons are ready put on Rocksteady and fire them away. Rinse and repeat this during the fight.

After you manage to proc Paralysis on Fatalis, you should move to the next build. Moreover, you should get 1 mount by using Jumping Slash. Do not forget to take a farcaster.

After changing to this build, your aim should be maximising your DPS and if possible getting an additional mounting

Hope this will help you in taking out Fatalis!
