It is likely that his presence will be perceived through these intermediaries unless circumstances force his hand. Tyrael is still feeling the effects of destroying his Worldstone at the end in Diablo 2. The mysterious artifact guarded Sanctuary from Heaven and Hell, and he now acts as a protector for the land on its behalf. Tyrael seems unlikely to lead any further assaults into Hell or go much farther in the Pandemonium Fortress
Diablo IV Gold, where he might offer advice similar to Deckard Cain to those who stay and listen.
Five different Diablo classes that can be played have been revealed so far, and they all represent takes on options from earlier games. With each of the games that has been released so far has brought something new to the table maybe Tyrael can be a hand in the battle that balances the sides, offering players the chance to take on angelic or demonic powers , in exchange for responsibilities to Sanctuary. This sort of mechanism could very easily build on the multi-tree development that was confirmed for the series.
It is unlikely that Blizzard will make Angels and Demons into classes, as the series focuses on characters stuck between them. In reality, though, as the one in the middle of Heaven and Hell Tyrael is in a position unlike any other in all of Diablo lore. He's likely to be playing a role of balance in the story, maybe even as a voice of reason instead of a partisan as the past. When he's forced into taking the side of his opponent, Tyrael has come to understand his role as a mortals, and that's the reason he'll participate in the events of Diablo 4.
The method used by Blizzard to specify your character's abilities in Diablo 4 is a blend of the method used by the studio in Diablo 2 and Diablo 3. As executive producer and head of the Diablo franchise Rod Fergusson put it, "Diablo 2 was like locking yourself into the game; you could respec one time per difficulty. With D3, you sort altered your appearance as if you changed your clothes. Everything was gear-based as opposed to skill-based
cheap Diablo 4 Gold."Fergusson added, "I think the fact that we have skills on the equipment [in Diablo 4] is really nice for experimentation -- as a sorceress I [might] get Blizzard [on a pair of boots] three levels before I should and I can try Blizzard to see if I actually want it."
