Gameplay Spoilers for The Legend of Zelda: Tears of the Kingdom
Holy Cow, I'm freaking overpowered now. So now that I've completed the Gerudo story and pushed SUPER hard through it, I was given Riju's Sage shadow.
Basically, you can create lightning ON DEMAND. I've taken out whole camps using her power just once, and mined an entire room of ore with a strike. Not to mention, she can fight with you AND is invunerable. I've watched her take out enemies galore. O_o
The tradeoff is a not-terrible charge time for the effect, and having to chase down the shadow, because she's got small weapons and will run towards enemies out of your range for starting the lightning charge.
I'm still very much in the "easy mode enemies" stuff right now, but I'm using some super powered stuff to take them out. Still low on hearts, but working on that.
This is FUN. :D
