When I level up, the screen shows me so many passives/actives/generators/spenders/runes. What I am asking is whether or not I am able to use everything that is available to me at my level.
For example, as a monk, I have unlocked all four spirit generators. However, many guides have been telling me to use two generators, such as crippling wave for AOE damage and FoT for single target. What about the other two?
I just do not understand how the system works, because it's not like I can level up CW/FoT to a higher rank every level.
The same question applies to runes. If I choose to use, say for example, Thunderclap with my Fists of Thunder, will I be able to use Bounding Light later on? Or am I stuck with Thunderclap?
Sorry in advance if this seems like a simple question; I am new to the Diablo series. And thank you for reading.
