With the Upcoming Assassin's Rework including Shaco, here are videos of a few Shaco Bugs.
This is playlist of 3 videos. 2 being the same bug with all champions it effects, and the 3rd being multiple current bugs/'features' to Shaco's kit.
The first 2 videos along with the first 2 clips of the 3rd video, show a Shaco W (Jack in the box) Interaction that cancels almost all movement abilities. In the 3rd video though, it shows Riven and Tryndamere having the ability to destroy the boxes without being effected by the box's fear.
The next bug showing in the 3rd video is a red trinket bug where a box will activate if dropped during the red trinket going off.
Next, with a change recently to the enchantment upgrades, Shaco's R (Hallucination) does not acquire homeguards when leaving the base like the real Shaco does.
Fourth bug shown is a bug where runes, masteries and dragon buff aren't shown/applied to Shaco's R (Hallucination).
The fifth bug shows that Shaco's clone does not get some item effects such as guinsoo's and the relic shield items, along with one not shown, the frost queen items.
Next is a bug where autoing as soon as stealthing does not apply the crit to the target you attack.
Last, a bug that isn't much of a bug and more of a 'feature' is cancelling an auto takes you out of stealth.
Along with these bugs, there was one I did not include. When pinging on the map with alt+left click, your clone will walk back to you. This might be because you're 'self casting' the movement spell that is Shaco's ult, but it is very frustrating when trying to ping an enemy along with moving your clone.
To add to this, some things that should probably be addressed: Shaco's ult being feared by Volibear E and Darius R, Shaco's clone cannot attack wards, boxes not having immediate cc (If you watch the 3rd video, the first clip while doing the intro Kha'zix kills me after being feared by getting an auto off)
Thank you for your time reading this and watching the video. Much love, have a good day.
