His presence will be Diablo 4 Gold detected through these intermediaries, unless circumstances take his hands. Tyrael is still feeling the effects of destroying the Worldstone at the conclusion in Diablo 2. This mystical object protected Sanctuary from Heaven and Hell and he stands as protector over the land as its successor. Tyrael does not appear likely to lead any further escapades into Hell or even go further in the Pandemonium Fortress, where he might offer advice similar to Deckard Cain for those who choose to listen.
Five playable Diablo classes have been released so far and all of them are alternatives to the earlier games. Each installment has provided something different, perhaps Tyrael will become a player in the battle, balancing the sides by providing players with the possibility to take on angelic or demon powers in exchange for duties to Sanctuary. This type of mechanic could be a natural progression from the multi-tree enhancement that was already made public for the series.
It seems unlikely that Blizzard will make Angels and Demons into classes, considering that the franchise is focused on the people caught between their way. As a mortal in the middle of Heaven and Hell Tyrael finds himself in a unique position ever seen in Diablo history.
He is more likely to be a balancing act in the tale, perhaps even as a voice of reason rather than taking sides as his former self. Even when he is forced to take the side of his opponent, Tyrael has come to understand the importance of mortals, and that's how he will most likely take part in the events of Diablo 4.
The approach of Blizzard's to speccing out your character's abilities in Diablo 4 is a blend of the Studio's approach to Diablo 2 and Diablo 3. As executive producer and head of the Diablo franchise Rod Fergusson put it, "Diablo 2 felt like you were locked in; you were able to buy Diablo IV Gold switch your specs every time you faced a challenge.
