The Flame King is a very easy beginner boss in DreamScape. This boss might be a bit challenging for new players, for with some pretty basic beginner gear you should face no problems.
The Flame King can be found in two places:
Sponsor Zone, also known as Ownercape Zone
Boss Teleport System.
Range is the most efficient way of killing the Flame King. Some common early game range weapons to use are the Assault Rifle and the Golden Ak-47. Since this boss drains prayer its recommended to bring White Glass Wings and bring some extra food, just in case.
Since the Flame King is a boss, it is included in the Soul System, converting all common and uncommon drops into souls. The Flame King, along with all other NPC's in Dreamscape, drops the Infinity Key and immortal stone fragments.
