Doom

Lucifer the Doom Bringer is a melee strength Hero with strong farming and laning capabilities. He has low starting Armor, but his abilities and high health allow him to lane effectively even while being harassed. A ruthless and malicious demon, this terrifying monster possesses demonic powers revolving around evil and death and is a towering force that uses his lethal abilities to annihilate his adversaries. His Devour ability allows him to consume creeps, gaining any powers that creep had. He is quite capable of farming in the jungles for quick gold and creep powers to absorb. Doom Bringer has been feared by many, particularly Invoker, due to his ultimate, Doom, which is known to deal intense damage and silence any Hero rendering their abilities useless. The Doom Bringer is an extremely dangerous hero due to his farming capabilities. If he gets buffed too much from items, he becomes a walking nightmare on the battlefield.

Tips

 * Doom Bringer has very poor Agility gain and one of the lowest starting armor in the game so it is essential to tank him up with armor items such as Assault Cuirass and Shiva's Guard to make his high HP go farther against physical attacks.
 * Be aware of heroes that commonly build Linken's Sphere as casting Doom on them will result in it being completely wasted. Cast LVL? Death on them first to burn the Linken's Sphere cooldown before casting Doom.
 * Cast Doom early in teamfights - the huge 15 second duration can render spell-dependent nukers such as Zeus or Lina virtually useless. Alternatively, if you can catch a hero carrying key support items like Mekansm and Pipe of Insight you can prevent those items from being used during the subsequent fight.
 * Make use of Devour's ability steal to give yourself and your team useful neutral creep auras like regeneration, swiftness or bonus damage.

Trivia

 * Several of Doom Bringer's abilities are inspired by Final Fantasy's Blue Mages. LVL? Death was probably inspired by the Level 5 Death skill. Devour, was an ability in Final Fantasy VIII who lets the user consumes monster to gain attributes, although it seems to be more aligned with Final Fantasy's IX's Quina Quen's eat and cook abilities in which this Blue Mage would actually eat his/her enemies in order to gain their spells and abilities. Finally, his ultimate, Doom, also shares the same name of another Blue Mage's ability, Doom, however the mechanics of each spell are different.
 * His name, Lucifer, is the name of a fallen angel who is known as the Devil in the Bible.
