The reward for defeating a possessed boss is either a mystery box or enchant potion, making them worthy targets to hunt.
Unlike other bosses, these bosses appear randomly in the dungeons and disappear after each fight, meaning the dreamer must defeat them within a single encounter. They also take coins from you if you lose to them. It is recommended that you carry at least three bags of Fairy dust with you when adventuring in these areas, if you want to have any chance of defeating these bosses. Ability to heal yourself is also a must. For this reason, players who use guns (such as Starshooters) will not be able to defeat them, because they only have the Aim ability, and can only heal themselves via healing potions.
The table below lists all the possessed bosses, their minimum level, and where they may be encountered. Note that you can encounter all bosses in all parts of their respective areas, for example you could encounter the Lake Demon in the first part of the Marsh when you are level 51. However, they do seem to appear more commonly in the more difficult parts of their areas (for the Lake Demon, levels 54 and 55).
|The Lake Demon||51+||Lakeview||The Marsh|
|The Rat Demon||56+||Junkton||The Sewers|
|Demon Captain||61+||Emerald City||The Forest|
|Demon Leader||66+||Emerald City||Thief Hideout|
|Demon Whale||71+||Oceana||The Beach|
|Demon H1N1||76+||Metreon||Robot Factory|
|Demon Senator||81+||Metreon||Rebel HQ|
|Demon Sandworm||86+||Phoenix||The Desert|
|Demon Jawba||91+||Phoenix||Base 13|
|Demon Dragon||96+||Mt. Killjoy||Volcanic Cavern|
There are no reports yet of encountering all of the bosses, thus some of their exact names are not known.
Boss HP is 200,000 at level 54 and rises by 50,000 every level.
Sheriff Graham gives out a mission to kill ten of these possessed bosses for a reward.
