Karamja was one of the first Achievement diaries I've started and it is the last one I have yet to complete. Expect for Ardougue Elite, I have everything else done.

 

I'm currently stuck on trading gems for a machete and catching a Karambwan. I may also need help on being the Champion of the Fight Pits and killing a Ket-Zek at the Fight Caves.

 

The other tasks I think I can handle with no problems.

 

Anyone got any tips on how to get those four tasks out of the way?

Catching a karambwan is pretty simple. Copied from tip.it's fishing guide:

"When you have completed Tai Bwo Wannai Trio quest and have the appropriate fishing level you can catch your own Karambwan which heals 18 each if cooked properly. First you need loads of Karambwanji for bait. Use a small net to catch them in the lake just south of the Tai Bwo Wannai village fire ring. When you think you have enough, grab your vessel and head across the log bridge and up to the north shore. Use a Karambwanji with your vessel to load it, then click on a fishing spot and away you go! Remember, you have to reload your vessel after each catch. Players who have at least started Fairy Tale Part II quest to access fairy rings, can use code CKR for the Karambwanji lake, and code DKP to reach the Karambwan fishing shore.

 

Note: If you've lost your vessel you can buy a new one from Tiadeche in the village; he will also buy raw Karambwan from you. "

 

For the gem trading, you'll need a goutweed tuber, 300 trading sticks, and 3 opals. You can buy all of this on the GE, but it might take a while. Gout tubers are annoyingly hard to get, so you might have to do jungle clean up until you find one.

 

To be champ of the fight pits all you need to do is take a friend to the fight pits and find an empty world. Kill your friend and you will be the champion.

 

As for the last one, you'll have to gear up and head into the fight caves. You'll have to get through 30 waves until you finally get to a Ket-Zek, so come prepared. I recommend bringing a rune crossbow & broad bolts, black dhide, guthans, and a few sara brews/prayer pots. Check out a fight caves guide for details.

as stated above, just for the tzaar caves, ull reach the 360 without problem and normally with some pray left

but to be sure take 2 extra ppots, some monks for whenever u might get hit and range away from a safespot

 

for the goudweet tuber, ull have to get 100% happiness anyways and while doing this u might get 1, otherwise put an offer @ max in ge for couple of days
