Find and talk to Brundt in the main building in Relleka with the quest icon.
To get a Fremennik Sword, you must not have completed the quest "Fremennik Trials", as you get it ( after much effort and luck) during this quest. You go down into the area to fight Koschei the Deathless, and you kill him the first 3 times, which is fairly easy. The fourth time, he is much harder to fight. If you die, you have completed this part of the trials anyway. If you win, he drops a Fremennik Sword.
You can try:As a First Resort..., Fremennik Isles, The Fremennik Trials, The Grim Tales, Icthlarin's Little Helper, Monk's Friend, Recipe for Disaster, Back to My Roots, Heroes' Quest, and Summer's End quests.
There are a couple I suggest, if your are F2P then train on white knights, if you are P2P train on Yaks (If completed Fremennik Trials quest,) or train on Rock Crabs.
The simplest way of getting to waterbirth island is to talk to Jarvald standing on the west most dock in Rellekka. If you have not completed the quest "The Fremennik Trials" you will also need 1k for travel.
You can find them at Fremennik Slayer Dungeon southeast of Rellekka.
You can obtain yak hairs in "RuneScape" by using the shearing option on a yak during the quest "The Fremennik Trials" or by purchasing them from the General Store in Neitiznot. Alternatively, you can receive yak hairs as a drop from certain monsters like yaks.
You could use the runescape websites questhelp feature or use a fansite's quest guide
To make a Fremennik round shield you must first complete the Fremennik Isles quest to actually make the shield you will need two arctic pine logs, a bronze nail and a rope. With a hammer in your inventory, you then click on the tree stump near the Neitiznot bank and select 'make Fremennik round shield'.
I believe the only requirement is 55 defence. You have gotta finish "The Fremennik Isles" quest too.
If you quit runescape...
