Shrines
Shrines include a trial or blessing, and at the end of it you get a spirit orb, which is like a heart piece or stamina fragment
Shrines are very important. They reward you with spirit orbs. Spirit orbs are used to get stamina and hearts. Hearts are used for survival. Stamina is used for hard to reach places
In BOTW, the maximum hearts are 18. The maximum stamina is 3 wheels. Hearts are used for defence (Duh). Stamina is used for things like running (Also duh). Here is a list of other things stamina is useful for.
Shirines sound good and all, but you’re probably wondering, “Isn’t it too easy to just get a spirit orb?” Well, they aren’t. You always have to do something to get a spirit orb. Even the ones that are blessings you have to do a quest. Here are some of the harder shrines.
Some shrines are very hard but the harder they are the more rewarding they are. Start out with the easier ones and the hard ones will become easy. You can always come back to them with the warping. When you go back into the shrine it will start you at the beginning.
