[Season 13.1b] Fiddlesticks Jungle Clear  

Clear path taken from this guy: www.bilibili.com/video/BV1NT4...
The clear in that video uses Absolute Focus and Relentless Hunter and is only a second faster, so I think my version is more optimized. If you do end up taking those runes, I think 2:58 or better is possible with better optimization.
The double camp is consistent. Just get familiar with where you have to click while zoomed in (almost impossible without zooming in, or at least highly inconsistent).
If you want to do this clear, you'll have to forgo placing a defensive effigy at the start of the match, so it has its trade-offs. It's very fast, though.
2:59 might be possible without Absolute Focus + Relentless Hunter if everything goes correctly. I had a couple clears where I entered Wolves area at around 44.2 instead of 44.8 like in the video, and I also got minion blocked by the Wolves here, slowing it down a little bit. Additionally, I also didn't transition from Blue to Gromp perfectly, which cost another 0.1-0.2 seconds.
If you find any potential optimizations, please let me know. You can contact me on the Fiddlesticks discord or add me on Discord (ioprocessing).
