Is there an after-cast delay in League of Legends? Specifically I think I've noticed it on Wukong. When I am using nimbus strike to harass, I want to use decoy immediately afterwards to try and stealth and run out of range again so I can harass without the opponent poking back at me. However it seems there is about a .5 second delay before I can decoy and in this time the enemy can usually get one hit or one spell off before I can stealth. I wonder if I just had a spike in latency when that happened or if there is a un-noted aftercast delay. Can someone with Wukong test this out for me?

    The reason why i can't test it again is because I dont own wukong and I played in during free week some time ago.

  • Are you using smart cast?

  • @Toast, yes I am. But i dont think it matters since decoy isn't a targeted spell.

  • There have been some previously reported bugs with smart cast and spell delays. I can't find any official sources, just mentions within the forums.

    Nonetheless, you could be genuinely experiencing lag, what computer are you using? I've found playing on my laptop reduces my ability to skill quickly, even with a strong internet connection. I usually play on a desktop with a direct connection to my router (none of this unreliable Wi-Fi silliness).

I can't speak for Wukong specifically, but there are cases of "after cast delay". Or, if you're familiar with fighting game mechanics, it's essentially "recovery" time from executing the attack. Once the recovery period is up, then you're able to resume your assault - otherwise, you must wait.

There's two different forms of skill "recovery" that are implemented in League of Legends for some skills.

The one you're probably experiencing is simply that there is a short recovery period after the resolution of the skill where you cannot act. For example (and this may just be what you're experiencing), Nimbus Strike has a tiny delay between when you make contact with your staff and when you can start acting again. There's a short delay after Blitzcrank purges his Static Field before he can start moving, and Ezreal's Arcane Shift has a tiny delay after you arrive before you can use another skill or attack. The logic behind this is essentially an extension of the reason you can't use skills or attack in the middle of the action to begin with - you're still in the middle of using the other skill. It rate limits your ability to chain skills instantly together. Contrast something like Tristana's Rocket Jump, where you can use skills even in mid-air.

The other form is that some champions, namely Sona and Udyr, do have a forced cooldown on all of their skills after using any single one. In their case, this is to simply rate-limit their ability to cast their spells sequentially - no song spamming, and no ridiculous stance chains.

  • Make sense! Thanks! And another champion with force cooldown is Udyr and his stances.

  • @Jay Udyr was free, like, twice in two months when I first started League of Legends, which I decided not to try him at the time. I have not seen him since, argh. But for the same reason as on Sona, it makes sense for him to have that cooldown system.

  • Any chance of providing a source to this? I attribute the "recovery" to the animation of the skill, which can normally be negated by immediately moving, using a different skill, etc.

    @Toast Not all things can be negated by moving - you can cancel some animations but not all. For example, you can't just move in the middle of Nimbus Strike - the "recovery" is merely the followthrough of the animation after what one might perceive to have been the end. But in reality, the motion is still happening. Compare flashing while still moving with a champion to Ezreal using Arcane Shift and then moving - there's a distinct pause.

  • Skarner's Crystal Slash, for example, has recovery with respect to using basic attacks, but you're still free to move and use other skills while the animation persists. Caitlyn, on the other hand, just about the moment her Piltover Peacemaker finishes firing you can start moving - its recover is slim to nonexistent.

(Was to long to add as a comment on the answer above so added as an answer)

The delay on ability's is technically called a Global Cool-down the time it takes for the spell to fully go off before your next ability is available you can auto attack during this time but not use another ability for .25 to .5 of a second depending on the ability used its why when you cast one you get a slight delay before the next ability goes off (The Term Global Cool-down originated from WoW and in that case is defined as the cool-down which starts every time you start to cast a spell, and it affects all of your spells. There are exceptions to this, however, as noted below. The basic rule of thumb is that if the spell affects the casting of the next spell, it will not activate the global cool-down.) But is the reason why you see a .5 second delay on the next ability you use as for example Wukong but i reiterate THIS DOES NOT AFFECT AUTO ATTACKS ON COOL-DOWNS


Nothing in Wukong's abilities mention an additional cool-down after using an ability (unlike Udyr). Remember that you're target-able while dashing forward, so an enemy with good reactions could target you then.

It could also be a latency issue, or some other hardware related delay.
