Queen of Pain is a ranged character. Her primary attribute is intelligence. The hero is mainly taken as a midlaner. Most effective in the early and mid game.
A fairly mobile hero due to the Blink ability, which allows Queen of Pain to start an initiation or escape from a chase, and the purchase of Aghanim's Shard will add it area damage. In the laning stage, the character is able to completely dominate her lane thanks to the Shadow Strike ability, which makes it difficult for enemies to farm creeps. Scream of Pain allows the hero to both farm forest and deal mass damage in team fights, and when combined with Sonic Wave, which can be upgraded with Aghanim's Scepter, the ability becomes even more dangerous.
The king turned to the captive demonologists, promising freedom to whoever could summon a personal succubus of torment and bind it entirely to his service. This is how Akasha came to our world. She brought the king painful pleasures, but in the end, people rebelled against the monarch and at the moment of his death, Queen of Pain was let loose into the world, freed to visit her sufferings on anyone she deigned to notice.
