Transition to Jungler

Hi,

Not really a part of the LoL community, just an avid player. But hi there.

I mainly play the supp role in a game. I actually like the supp role the most. Many of my champs are geared for that role, some of which people won't expect. My main champ is Lux. I like to play a ranged game and like sniping, either getting a kill or an assist.

When it comes to playing ranked, I know climbing as a supp is impossible. I'd like to try jungle since it's like a roaming supp, but know I need to learn tanky characters. I'm a fan of Ekko and Kayn so far.

Aside from learning champ strengths, my real weakness is how to jungle. I have no clue. I kill monsters for how long before a gank? How often? When should I attack epic monsters? Etc. I can only practice technique so much against AI, but PvP can rely on a good or bad jungler.

So any help or tips is/are appreciated for someone transitioning from a ranged supp to a close-combat jungler.
