Warlock is a ranged character. His primary attribute is intelligence. The hero is mainly taken to the easy lane as a support. Most effective in the early and mid game.
Despite being a support, Warlock is a very valuable ally in team fights. Fatal Bonds increases damage against the enemy team, Upheaval slow enemies in a large area, and Chaotic Offering is almost always a good spell to initiate a fight. The character's ultimate is useful when demolishing buildings and can be upgraded with the purchase of Aghanim's Scepter. At the laning stage, Warlock is very useful due to Shadow Word, and with the purchase of Aghanim's Shard, this ability will also increase the character's effectiveness in team fights.
Demnok Lannik was tireless in his pursuit of lost, rare and forbidden tomes, which has become a vital necessity for him. He surpassed all the warlocks of the Ultimyr Academy and began writing his own work called Black Grimoire. It will undoubtedly be instructive.
