I got so many questions about Hextech Gunblade, Bloodthirster and more.

First of all, I think Riot didn't do a good job explaining their game mechanics. They programmed it, it should be so easy for them to just explain the basics.

So, my first question is about the healing mechanics on and . Since heals 33% on all dmg dealt, if you equipped both and red buff, would red buff's burning effect also heal? If so, how does it work? Does it keep healing for 5s? Also, what about the demon's true dmg, is it also going to heal you if you have ? What about and Ionic Spark together?

Since is for "all dmg dealt", I asume is for basic attacks even though on the describtion it only says "attacks". So my question is will heal you from abilities that apply on-hit effects such as ?

Also, which one will heal more if equipped ?

My second question is ap items on champs such as , ,and . Since their abillites don't deal dmg, are those ap items such as increases their healing or shield?

Thank you for your time reading this, good luck!
