The following items should almost always be brought with you when you fight dragons.
- Anti-Dragon shield/Dragonfire shield or Super antifire potions. Having one of these items is a MUST, otherwise, you will find yourself in your selected respawn point very quickly.
- Food - Lobsters or higher in case you get within melee range of the dragons or your antifire potion runs out.
- Beast of Burden pouch e.g. Spirit terrorbird, War tortoise (Note: Be aware that if you exceed the familiar timer, any items stored will be dropped).
Example Setup and Inventory:
All four chromatic dragons have a weakness to bolts and therefore it is highly recommended to use a crossbow along with an Anti-Dragon shield. All four also attack with both melee and magic in addition to their dragonfire, meaning that you should stand several steps away when attacking a dragon to negate their melee attack. Furthermore, where it was possible in the past (pre Evolution of Combat) to range the dragons from behind a safe-spot, this is no longer the case due to the magic attack, however wearing dragonhide armor should provide sufficient defence against this.
Green dragons are found in three locations in the Wilderness: level 15 (north of the Goblin Village), level 48 (south of the Lava Maze), level 26 (east of the Bone Yard). However, killing them here is not recommended due to the obvious risk of player killers. If you do choose to kill Green dragons in the Wilderness, then using the location in level 15 Wilderness above the Goblin Village is safest due to the close proximity to the Wilderness wall and make sure you don't take anything you're not willing to lose.
The Chaos Tunnels:
The Chaos Tunnels are the safest place to kill Green dragons, however you will have to briefly enter the Wilderness to access them. To reach the Green dragon room in the tunnels, cross the Wilderness wall north of the Grand Exchange and head directly northeast until you come across a rift. Climb down it and once inside, make your way through the portal to the relevant rooms (21 and 49).
Ancient Cavern (Brutal Green Dragons):
An alternative to fighting normal Green dragons for those who want more of a challenge and more rewarding drops is to kill Brutal Green Dragons in the Ancient Cavern. These are much stronger than the lower level dragons, but are more easily and safely accessible if you've completed a portion of the Barbarian Training and unlocked the use of Fairy rings through A Fairy Tale Part II.
The best place to kill Blue dragon is in Taverley Dungeon. To access their area, you will need either a Dusty key or 70 Agility. If you find that the main room is too busy, then you can access the resource dungeon to find more dragons (requires 60 Dungeoneering.
Heroes' Guild Dungeon:
Gu'Tanoth Ogre Enclave:
The Ogre Enclave under the ogre city of Gu'Tanoth contains several Blue dragons (requires partial completion of the Watchtower quest to access).
Note: Do not attack Ogre shamans in this dungeon. They are invincible and can hit up to 3, 000!
Red Dragon Isle:
Red Dragon Isle is located in level 51 Wilderness and very remote. It is not recommended to kill Red dragons here under any circumstances.
Evil Chicken's Lair:
The Evil Chicken's Lair in Zanaris is the best place to kill Black dragons due to its close proximity to a bank, however accessing the lair requires completion of the Sir Amik Varze subquest of Recipe for Disaster.
There are a couple of Black dragons located towards the end of Taverley Dungeon. However, if you plan to kill them here then it is recommended to have either 70 or 80 Agility so that you can exit the dungeon quickly to bank via the shortcuts, otherwise it's a long run back and forth.
