Maglor was Feanor’s son and is the last of the house of Finwe. Technically, he is not dead but He is a wanderer after he tossed the silmaril into the sea.
I believe that Maglor would randomly spawn on the northwest coast of middle earth or within a few hundred blocks of belegear. He would be wandering about and talking to himself. He would possibly acknowledge the player if the player attempted to speak to him. He would defend himself if need be. He could only spawn randomly and only spawn once. (Unless you used commands to summon him).
Maglor would be similar in appearance to Feanor. He would have the similar complexion and the piercing eyes and black hair. He would be taller than normal NPCs. This relates to his father, feanor, being a commanding presence. Maglor would have a charred a from the silmaril. Maglor would talk about life events, laments, and the silmaril in his ramblings.
Maglor could be a mini-boss style character with 120 HP and some kind of weak regeneration ability. He would be using a dark version of lindon armor with more spikes and weilding one of Feanor’s cruel blades. This sword would do 12- 15 damage and the armor would provide full protection without scrolls as this gear was made by Feanor himself. During battle, he would keep rambling though he would be talking more about servants of Morgoth and balrogs. Maglor would have a sweeping attack and quick dodge ability(akin to slightly faster than an orc with strong draught). His eyes would also be red, reflecting the firey spirit of his father.
Maglor would be a boss for evil players and will respond with a warning when hit once and attack when hit twice. When he dies, he will go up in an engulfing plume of smoke and flame, like his dad did, and he will leave a small crater and sulfur ore when he dies. In this crater, Maglor will drop the armor and sword of Feanor. He would also drop lord items like a palantiri or banner of his house. He will also drop elven bones and murvior. Upon Maglor,s defeat, the player will loose 500-1000 reputation with the high elves. They will also get the title and achievement, of flame, and would gain 500 mordor reputation. They would also get a custom shield. This shield would be a cracked and bloodied shield with the house crest of finwe.
Yes, I know that he is a cannon character but Maglor is not often thought of and I think that it would be cool to include this in game as a nod to this aspect of the silmarillion and another boss fight
