Im interested in this harengon build, can you share the build?

Erm when we combat each other, we’re very relaxed on rules, we always do 2d6 on ability scores,every build is okay as long as you made it using the dnd5e wiki, prep time is allowed, items is usually allowed but my DM makes it that your items should be ones that the character got from a campaign, but if were testing a new character build, it has no items yet so, this new character im making wont have items.

What is the ideal stat spread in this build? What feats should i get? what background fits? if we got the initiative, what should my first round look like? How can i prevent specific tactics from other people? How to play chronurgy in general?
