$500 "DLC" 

i manage to join USJ event 1x from SOS.
but full palico gear + azure longsword require 6x....

normal or extreme behemoth ?
I would highly recommend play with a tank, it just makes life much easier.

I can play as tank or cluster dps role
Normal behemoth if can be cleared with just 3 players (1 tank with 2 cluster dps).
Extreme behemoth is a totally different beast, definitely need a team of 4.

Any weapon is fine, just attack his hind legs and careful when he do his spin move if you are using melee.
I manage to clear normal behemoth with another friend long ago, 1 CB and 1 lance, took us 30 minutes though haha.

I did some behemoth run yesterday with a group of friends, around 13 minutes per run (1 tank 3 cluster).
Usually I will online around 10pm-1am on most days.
Pm me your psn id if you need a buddy to fight behemoth, I’ve cleared almost everything and just waiting for new events these days.
