Pyke bug list as I've seen in game
I've played quite a bit of Pyke since his release and just wanted to fill in riot on some of the bugs I've found with him.
Passive: Usually around level 12-13 this seems to heal for nearly 100% of damage taken despite the math saying otherwise. I've noticed this many times and wondered if the calculations were messed up somehow. I've frequently left fights and healed back to full hp.
Q: If held until the very last second you can throw the hook even after the charge animation has canceled. This can be quite misleading to the enemy team.
W: Movement speed bonus is lost instantly upon leaving stealth. (This may be intended, but I still believe it should be changed as I run in to it most frequently when using W for movespeed and then following it by activating sweeping lens. Reversing the order of activation allows the movespeed and sweeping effects to both be active.)
E: Hitbox seems to have some issues when you're nearly right on top of a champion. I've been quite surprised before when a stun landed and I wasn't expecting it to, and quite baffled when a stun I was sure would land ended up missing.
R: Cooldown reset is lost if Pyke is killed with a revive passive active (Guardian Angel, Zilean R)
R: If an enemy dies immediately after pyke lands, but not from the damage of his ult, the gold will be granted to an ally but the ability will not reset. (The two are meant to be triggered by the same circumstance so one should never trigger without the other) This has happened to me several times. To recreate the bug simply get an enemy champion to just above the execute threshold of pykes R. Second, ult that champion and time someone else to hit them moments after pykes R. Pyke will land without killing the target, then they die to the other team mate.
R: May sometimes 'fake reset'. I had this happen only once, where I successfully executed someone with my r, however no gold was granted to an ally and the ability icon became dark as if it was on cooldown, with the reset clock ticking down over the darkened icon. The ability was unable to be cast during this time. When the reset window ended the usual ability cooldown timer replaced it. I'm uncertain what caused it, or how to reproduce it, as the only time it happened I hadn't done anything special, and the kill I got with the ability was fairly standard.
R: In ARURF gamemode, the ult cooldown is triggered upon activation of the initial cast, and not upon the end of the reset timer. This lead to some very interesting interactions, my personal favorite being a moment where I ulted one person twice in a row, the first being a recast from previously executing someone, the second being a new instance of the ability. This happened because the reset timer was set to expire only a moment before the base cooldown ended. If the reset lasts long enough however, reactivating the ability during the reset window can trigger both cooldowns simultaneously.
R: Seems to often have issues properly displaying the amount of gold granted to teamates. I remember this being supposedly fixed during a patch, though I've still seen issues with it.
Pyke being in game: Since pykes introduction there seems to be some issue with champions appearing to assist themselves in a kill, or even assist the enemy in a kill.
These are only the bugs I've encountered in game, if anyone knows of others please don't hesitate to post in the comments.
