Necrophos

Rotund'jere the Necrolyte is an item-dependent caster Hero who can take on multiple roles depending on his teams needs. His skills are most effective in team fights where he can damage enemies and heal allies simultaneously, while picking off key enemy heroes with his ultimate. Necrolyte is most dangerous when his enemy is severely injured, instantly killing them with his ultimate while recovering his Mana after killing his foe. Whenever Necrolyte walks, death follows, slowly draining the vitality of his enemies and killing them, all while enjoying the pleasure of pain and gaining life.

Necrolyte is naturally fragile, and he's not a strong physical attacker nor spell caster too, thus, he is a more difficult hero to utilize. However, he is more powerful in levels and item advantage, thus, building health and mana boosting items can make Necrolyte more dangerous than he already is. The fact that he can annihilate Tanks and severely injured heroes is a great characteristic for him and any Intelligence hero. He is recommended for intermediate to advanced players.

Tips

 * Taking one point in Heartstopper Aura in the early game allows for harassment of enemy heroes by means of simply standing near them, as you would in early-game laning.
 * Only use Reaper's Scythe for a sure kill, as the idea is that it will return its mana expenditure. There are some exceptions, Reaper's Scythe can destroy enemy channeling abilities like Black Hole, Freezing Field as it's stunning effect can pierce through Black King Bar. Sometimes, Reaper's Scythe is a tool to stop an escaping hero in a gank. Therefore, depends on the situation, the damage aspect and the disable aspect of Reaper's Scythe should be used effectively.
 * Necrolyte can very easily be built as a tank and in most circumstances should be; gear for Strength (he does not need Intelligence owing to his two bread-and-butter offensive abilities being percentage based) and consider a Vanguard instead of or in addition to your Mekansm. He should be built as a tank because he needs to stay alive in violent encounters to heal his allies, and also because the longer he is alive for, the more damage his aura will do.
 * Necrolyte is an extremely effective counter for invisible heroes as if they stall before they attack his aura will whittle down their hp, and his Reaper's Scythe will prevent them escaping via invisibility before they die. He is also very good against heroes with abilities that deplete their own hp, such as Pudge and Huskar, but in order to withstand their assault he must be built as a tank.
 * A Dagon is effective at finishing off heroes, if you feel unsure whether you're Ultimate can kill your enemy instantly. Only recommended against tougher and fragile heroes and upgrade it to lvl. 3 for you to spare your gold to buy other important luxuries.
 * Aghanim's Scepter can be purchased on Necrolyte and will increase the damage ratio to 1.2, this means that Reaper's Scythe will deal even more damage to more durable heroes, to calculate the damage of Reaper's Scythe. Multiply the missing health of an enemy (Ex. Axe has a maximum health of 3,900 and he lost 2,200 health, multiply 2,200 by 1.2 and the damage of Reaper's Scythe will be 2640, ignoring magic resistance, which is already lethal enough to kill him.
