Malphite can "Save" w for later by stopping the first w attack midway agiasnt a monster, minion or tower, and then the effect will trigger on his next basic attack nomatter how long you wait, this also means that you can attack (first W attack will activate) and then you can use w agian to do the first w basic attack agian. Although this isnt the most important bug, it could definetly be exploited by people.
**How to do the bug**
1. Use w
2. Basic attack, but then move at almost the same time you basic attack
3. Wait until your normal five seconds of empowered basic attacks run out (Dont do anything)
4. Now you can basic attack any target for an empowered attack, meaning you can basicly use w twice
In terms of how difficult this is to pull off, well i whould say 7/10 times you try you can pull it off as long as you have praticed it for a bit. This is how it looks when you stop the attack https://cdn.discordapp.com/attachments/638738773605351437/642101409071759409/unknown.png and in this one you can see me using the saved w https://cdn.discordapp.com/attachments/638738773605351437/642102142659854347/unknown.png
