Yes we all know that Attacking a turret will grant you extra gold when it dies.
Now my question is a bit weird: What happens if you don't deal any direct damage to a turret but you buff an allied Champion or minion that finishes off a turret? Does that count as a turret assist? I know that if you shield a turret as Janna and it finishes off a champion, you will get the kill even if you haven't dealt any direct damage to the killed champion. Is it the same for other buffs on other targets?
For a more vivid description: 3 Scenarios with Soraka (I don't like her she just has some nice buffs)
- I'm At my base and I need 50 gold. Now waiting isn't really effective but luckily Ashe is about to destroy the enemy bottom turret so I use my ult.
- Me and Ashe are mid and we're about to kill the turret. The enemy Syndra approaches and Ashe drops really low. I accidentally heal the Cannon minion that attacks the turret instead of Ashe but at least the turret goes down. (I didn't throw a banana at the turret)
- Ashe Ragequitted because I heal minions and use my ult randomly. I'm alone at the bottom turret but I don't want to go too far in So I just heal a random caster minion that is attacking the turret and then I leave. The turret dies within 10 seconds.
Now in which of the 3 above cases would I actually gain bonus gold?
