for bow - make sure you charge your shots to the max before you shoot. pierce shots work well with him. when the arrows begin to dip down, damage becomes lesser and lesser so make sure your distance is correct (try to hit him before arrows arc down)

for bowgun - don't shoot from too far. the ideal distance is about 2 - 3 rolls away. shoot pierce, or bring a fire gun.

finally slain gobul!! took me 30 minutes to do that + 4+ hours or retrying. feels good man.

I always do that.
Set trap beside them when they are sleeping. Shock them awake and throw the red bomb.
But sometime its mafan if they rest at area 8 and i already weaken them at area 4.
They need to limp a few area only reach they sleeping place and kinda accidently kill them.

Capturing monster always have more loot than killing them?

When they are in the trap...using your weapon to damage them also counts as trapping

Speaking about traps....
I was at port quest...hunt an a.rathalos
Fight until he cabut to sleep,on my last life,low health
I set a trap next to it
Suddenly it woke up by itself,but not yet trapped
I run...it screamed...
I got stunned ,only it stepped into the shock trap
When I recover from the stun,I rush back and threw 1 tranq bomb....hit...
Threw the 2nd one, it escaped before the tranq landed.....
Proceed to slaughter me

seriously?  btw I tod blur_goofy last time got play wii version. you can always use dragonator there in case you can't hit much damage on that monster.

keep poking his face area - that hurts him the most.

Hmm.. maybe I was too late.
Guess I try it offline then
