Enemies are mobile in-game sprites controlled solely by programmed Artificial Intelligence, and seek to attack the player until the defeat of the player or itself when it is provoked; there are currently eleven enemies in BrowserQuest, with the addition of the Wizard in BrowserQuest Extended. Enemies are generally categorised into two types based on their A.I programming, with the latter being the most numerous: neutral, where the enemy does not attack unless attacked itself, and hostile, where the enemy attacks when it detects the player.
Rat[]
The rat is found only in the village and does the least amount of damage to the player.
Beach[]
Crab[]
Crabs are found throughout the beach in the southern area below the starting village, and can drop Axe.
Forest[]
Bat[]
Bats not hostile and deal rather low damage.
Goblin[]
Goblins are small, green creatures that spawn in groups.
Snake[]
Snakes are... snakes. They spawn in rocky, but mostly grassy areas.
Skeleton[]
Skeletons spawn in a rockier area. There are: Normal Skeletons, Greater Skeletons, and Skaldor. The Boss spawns in the volcano area far from the village.
Ogre[]
Ogres are large, light blue creatures that spawn in grassy, but mostly rocky places. They also guard caves.
Evil Eye[]
The evil eye is a large eye. They spawn throughout the area, and deal low damage.
Spectre[]
Spectres look like the grim reaper and do considerable damage.
DeathKnight[]
Deathknights accompany the skeleton king in his throne room. This is the only area where they're found.
Skeleton King[]
The Skeleton King is the boss of the game! Defeat him to obtain his golden sword and a chest near his throne containing Golden Armor - the second best equipment in the original BrowserQuest game.
