When it is on land EXSAUSTED, you aim for the head, when it is in rage mode, attack the back and tail, normal mode, go crazy (anywhere).
After you complete the 4* quests : Lost in blue and Leader of the ice pack an urgent quest will appear. In this quest you have to repel a lagiacrus, this is easy as all you have to do is hit him loads of times. After he runs off some new quests appear. Kill of the rathian in the "dragon lady" quest. Another urgent quest will now appear. This quest ("Fell the Lagiacrus") requires you to kill the lagiacrus.
You can't. You have to kill it for rank 4 offline urgent quest Use lance and all will be well
Lagiacrus!! Metal conducts electricity, its hide is too tough for some puny assault rifle and it has massive, crushing jaws!
ITs thw chest a "lowest part of neck"
when you have repeled the lagiacrus and you are on the five star quests you can forge a bone long sword.
Once you have succesfully killed a lagiacrus, the third ship will appear.
while rathalos can fly and lagiacrus can swim i think that the rathalos could because it has the stealth advantage and that rathalos kick butt well not mine with full vangis but well you know I dont know how this will help new hunters it might discourage them but well i got nothing...
So use a lance, a rugged lance in a fact. So pack a shock trap and a pitfall trap incase he goes on land. Bring some large barrel bombs plus, and some mega potions, wear Gobul armor and upgrade it as much as it can go. Hope this helped.
After you do accidental investigation (hunt a gobul), then talk to the argosy captain(make sure he went to the hunters realm, then go talk to the wyverian artisan and he'll say he the argosy captain told him how to make long swords. the first weapon you can make is the ananta boneblade. later after you kill lagiacrus you can make thunderclap and so on etc.
