Kill

Eggs, hatchlings, adult dragons, dinos, and chickens can all be killed. Only Leetle Trees cannot be killed.To attempt to kill a dragon or creature, select the "Kill" option on its action page. A player can only kill five dragons before he or she must wait about two weeks to kill more.

Killing an Egg
A killed egg appears as the jagged bottom half of an egg. Dead eggs remain on the scroll on which they died for two weeks. Killed eggs count as living eggs (and thus are capable of locking a scroll) for 24 hours, so typically it is preferable to abandon an egg rather than killing it. Occasionally, attempting to kill an egg will hatch it; this is known as forcing.

The message that one sees when successfully killing an egg, is as follows:

"You take the egg and smash it on the ground, killing whatever was forming inside."

Leetle Trees
It is impossible to kill a leetle tree. You can still click the "Kill" action, however, when it is clicked, this message shows:

"The leetle tree is too cute to kill."

Killing a Hatchling
Once a dragon becomes a hatchling, it becomes harder to kill as it will occasionally evade the blade. If this happens, a player cannot attempt to kill the hatchling again for another twenty-four hours. Dead hatchlings appear as tombstones and count as alive hatchlings for 24 hours. Sometimes you can use a magic spell to revive the hatchling. On Halloween, reviving a hatchling may create a Zombie Dragon.

Eggs and hatchlings that have recently died or were killed can be found in the Graveyard

The message that one sees when successfully killing an (unnamed) hatchling, is as follows:

"You take your blade and stab the hatchling, watching the life slowly leave its eyes as it stares at you, wondering why you betrayed it."

Killing an Adult Dragon
Adult dragons can be very difficult to kill, meaning that they can be very prone to dodging your blade ("Dodgers" cannot be killed for 24 hours after a dodged Kill attempt; they will continue to dodge the blade). Because of this, most players who no longer wish to have a certain adult on their scroll release that dragon to the wilderness instead of trying to kill it. Additionally, like all other stages of growth, the tombstone resulting from a dragon's death remains on the scroll for two weeks. Like hatchlings, a revive can be attempted and on rare occasions it will create a Zombie Dragon.

The message that one sees when successfully killing an (unnamed) adult dragon, is as follows:

"You take your blade and stab the dragon, watching the life slowly leave its eyes as it stares at you, wondering why you betrayed it."

Killing Cooldown
You can kill 5 dragons, hatchlings or eggs every two weeks. An unsuccessful Vampire bite is considered killing. The death of egg or a hatchling from illness or negligence isn't considered killing.

There is a confidential possibility to kill 6 dragons (one over the limit). For this purpose, after killing four, it is necessary to open the kill dialog in two different windows of the browser. It is not known whether this is a bug or an undocumented possibility. To use this possibility it is recommended to open the action pages of all the dragons you want to try and kill before killing the 5th dragon. If the 6th dragon dodges the blade, you will not be able to open any more action pages, but if they are already open, you can try the next dragon.
