This is the inventory you should have when you are using the ranging method to kill skeletals.  * Mind shield: This is going to be pretty crucial to avoid getting hit by their special attack. Only use it when you are coming close.  * Ranging potion: You will need a ranging potion or 3 (depending on how long your trip will be) to boost your accuracy and damage while fighting. You can also use a divine-ranging potion here if you have the money. This is a bit more expensive.  * Prayer potions: Bring about 4 to 6 prayer potions depending on your prayer level. Skeletal wyverns drop prayer potions too, so if you are lucky you will not run out of them. Use these to protect from their range attack and boost your damage with a sharp eye, hawkeye, or eagle eye.  * Food: I would bring sharks or some food around that level. Pizza is also a good choice here.  Wyverns also drop quite a lot of lobsters, so you have good odds that your food supply will keep being refilled.  * Bone crusher: This will automatically bury the wyvern bones. Which will save you some time and help you train your prayer. If you have not done the diary requirements, this will only give half the prayer exp. So take that into account when choosing this over burying them.  * Herb sack: This is useful for all the unnoted herbs they drop. If you are going to stay awhile, this is essential in making the most of your drops. They often drop 3 at a time, so if you do not bring your herb sack, you will have to leave a lot of herbs on the ground.  Nature and fire runes - You should bring a nice amount of nature and fire runes. Skeletal wyverns drop a whole lot of alchs that are essential to make a lot of money here. You can also bring a rune pouch to save an inventory slot and have an additional spot for one rune-like the death runes they drop.
