I just got 77 skeleton wyverns as my slayer task for the first time just now. I have never killed them before so i have no idea what to bring, what familars to use ect... Could someone please be kind enough to tell me how to kill these efficently without to many bank trips?

Without a unicorn it will probly be 2 trips. What i used to do is bring a bird or tort full of good food, wear bandos or verac skirt and torags top. bring bunyip for after

 

I flashed piety. never found dfs that much of a use there, but better then mind shield if you use a dfs normally use it, if not dont buy one for this task.

 

thats it in a nut shell

Erichermit's topic has the most comprehensive guide to ether ranging or meleing these guys. You can find it here: Misunderstood Monsters

 

Personally, I don't last too long and kill around 15 a trip and bank all the bones. Thats with a terrorbird full of food+ Super atack/str. Bring something for your special attack bar and use pray boosts for that special. I'm not too high leveled tho so you may not want to bank the bones if you can stay longer than your inventory would permit.

 

There is an altar and an obelisk on the way if you are running from draynor to the dungeon- so no good reason not to use a familiar and prays for your specials. Also the Lumby ring is a good fast tele if you get in trouble and doubles as a pretty quick banking method. The fairy ring is faster however you loose an inventory space as you should keep a quick tele in your inventory.
