whats a good way to beat gobul?

Use peco weapon. Or use a great sword, hold the wii remote up, attack, but wait for the inner glow to get bright. You will hear a ching sound. That attack has 4x the normal damage. Do not use plume flint. I died twice when I did that and I had full barroth armor. Use the ludroth bone sword plus. It is water element but water will do damage even though it resists it

every time he looks at you while your attacking roll/swim/strafe to the side. when he puffs up hit him in his underbelly or tail. when he runs to go rest,while hes asleep hit him>>>>NOTE
stun traps work under water :3

Right my plan...this invloves some hard work but rewards you with breezing through the later quests(including lagi) right... Once you get to the peco get some peco weapons and stuff and head out online, there just do loads of quests till you're level 8 then kill barroth level up to 17... Kill lagi (teamwork required here) then keep killing the rath and ian till you can make their longsword think it's 'longsword fire'or summit but it's got decent attk and a lot of fire attrb so it's helpful. Then go back offline and choose the gobul quest. It doesnt matter exactly what armour you have but since you have alreaady killed the gobul online you can get gobul armour or just mix it for high defense. If it was youre first time then go to area 6 (shortcut through back of camp)then after the video... Abandon(it helps alot)
After youre first 'attempt' go to area for but don't dive in use a frog to fish. Eventually the gobul will rise up don't PRESS ANYTHING!!! You will automatically start pulling the gobul. After you few times of fishing it out youll know where it lands so you can place traps bombs ect. But as soon as it land start attacking it with the wyvern blade fire(thats what it's called)at the sides or if you want the face. Once it get up then attack it around the base of his tail which is the place where youll take the least damage.after a while hell be weak and start limping towards area 3. After a minute or something hell burrow under the sand and dissapear. Dont panic hes only gone to area 8. Go there as fast as you can the go into water and near the entrance therell be a mound with reeds or something and random burts of bubbles carefully go and put a trap down. If you don't have a trap just hit it and it should go flying into the air and come back an itll be on it's back for a bit. Don stop attacking and then there you go youre first(well maybe 4th) gobul ;)
