In fact, I wanted to say that in Hogwarts Legacy there are no important choices that determine the fate of a particular character. Really. No one. Everything you do is scripted. You choose one or another option, the game will still lead to what is planned according to the scenario. So relax and have fun, make whatever decisions you want.
On the example of unforgivable spells - their study will not lead to anything bad. As is the application. So why deny yourself the Avada Kedavra, which allows you to kill any opponent with one blow?
The action game also received a content update.
