Question about "channeled abilities"
As a Janna main, I always shield my Caitlyn whenever she ults for the bonus ad... but I've wondered when the bonus ad actually takes effect, should I use it before she ults, while she's ulting, or when the bullet actually hits.
I also wonder the same things about buying in fountain if you have a global ult such as Ashe, Ez, Jinz, or Draven. If you buy an item that would increase the damage of your ult after you have already ulted, but it is still on the map, does that ult get the bonus ad/ap? And finally if level up a "channeled ability" as you channel it (including Lux's e, Janna's tornado), does it increase the effects for that channel?
Just something I've always wondered.
