have 2 questions

1. I’m stuck at 3-9 how in the world do I fly? Is it gear or what I read somewhere it’s left left attack or right right attack nether worked there’s only walk left o walk right and attack.

2. how do I get them elements I don’t see it in store or not even one drop from monsters or bosses and so on

The sad part is there’s very little information online or when I goggle it

Thank you
