Cobra Bastion

The Cobra Bastion is the fortress of the Order of the Cobra. It's similar to the Falcon Bastion both in structure and in story, since the leader of the Order of the Cobra, Scarlett Etzel, is the sister of Grand Master Oberon. The Bastion can only be accessed by players of level 250 or higher.
The following secrets are hidden in the Bastion:
* The Order of the Cobra Compendium is a collection of documents found in the bastion that tell the story of the Order of the Cobra.
* You will find several Brass-Shod Chests in the Bastion, which can be used once every 24 hours. From them you can get a items such as Cobra Crests, Life Rings, Death Rings, 8 Platinum Coins, Gold Ingot, Banana Chocolate Shake and others.
* If you use a Flask with Snake Poison on the Large Cauldron on the second floor, , all the Cobras will start spawning with 2000 fewer hitpoints. The effect lasts for 30 minutes.
* Sometimes while on the Bastion Island several Strange Rats may appear at once at the character's position. It may be connected with the Cobra's Curse.
* While killing the minibosses, there's a small chance that Ugly Monsters will spawn. If they do, you should kill them quickly, as they may drop any item of the very valuable Cobra Set. 
* Sometimes when walking around the Bastion while another player is killing Scarlett Etzel, you'll receive several orange messages from Scarlett herself. These messages seem to mention several things they character has done in the game, such as taming a Midnight Panther and creating a Ring of Ending. After these messages you may also see a display of The Cube Effect.
* You can find the Key 0303 to unlock some of the Bastion doors, including those on the floor its found.
* You can find a vial with oil inside a chest on the ground floor. It can be used to light on fire the vines that close the entrance to the 4th floor from the ground.
* If you move Gaffir's corpse to the Fire Basin at the center of his room, and then step on the carpet with the price tag, you'll be sent to a secret room where you'll find the last part of the Chess Game moves.
* On the basement, you can reach the room with a Cart Packed with Gold after defeating Custodian. If you protect the Cart from the Cobras and clear the path from Clutters on its way, you can kill it at its destination where you can supposedly get a valuable loot. Furthermore, the Cart will some times drop some Wheel Oil which can be used on it to jump a few tiles.
* If you toss a Gold Coin, Platinum Coin or Crystal Coin on the floor of the balcony, , several Light Effects will be displayed, as well as this message: .
