Talon mains, we're onto you! Talon has been slowly but surely racking up bugs, and it has been giving the champion an unfair advantage, but Reddit is here to compile them all and save the day.
Talon has been bugged ever since his rework back in 2016. Although the bugs, then, weren't major, they haven't been properly addressed to this point and have been adding up to an unacceptable amount. The bugs go as follows, in the order of their importance:
Abilities visually apply a fake Blade's End (P) mark even if the ability is negated by a spell shield or Fiora's Parry. This has been occurring ever since Talon's rework in Patch V6.22.
Melee Noxian Diplomacy goes on cooldown as soon as it starts casting, before even dealing damage. This is wrong behavior for a single-targeted spell with a cast time because when it's used on a target that becomes unavailable, such as death/invisibility/intargetability/stasis/out of range or sight, in the process, it stays on cooldown. No other ability works in this counterintuitive and unconventional way. This has been occurring ever since Patch V11.1 when the ability was recoded in order to stack Tear of the Goddess.
Assassin's Path gets interrupted by displacements even when protected by a spell shield. This has been occurring ever since Talon's rework in Patch V6.22.
Shadow Assault's blades disappear when the target they are converging on goes intargetable or vanishes. This has been occurring ever since Talon's rework in Patch V6.22.
These and many more can be found on the Rift, and on Reddit, with the Reddit user TH3RM4L33, compiling most of them, and causing League developers to take notice.
