On the Poppy VO; got the Needlessly Large Rod lines figured (I know. I was in disbelief when I tested that one.) and attacking dragon lines. The others I'm a bit stumped on.
"To the hero!"
"Fuel for the quest."
These didn't play when using any of the flasks, elixirs or health pots and I couldn't figure out a proper trigger.
Wait, you're here? I thought you were there."
"Didn't I just knock you away?"
Can't confirm, but I feel like these are for Ekko, specifically when he Chronobreaks after being hit by Keeper's Verdict. Will likely have to test that one with you.
"You should you wanna do this? You don't even have a weapon."
"That's not a hammer! This is a hammer."
"Look at all that shiny armor. Sorry I gotta mess it up."
Trying to figure these. In my mind the Hammer one is directed at Jayce, considering he's the only other hammer wielder (Morde uses a mace so he doesn't count). The top line's likely directed at someone either with no weapon or with an unorthodox weapon. Jax springs to mind as a wrote that last bit. Last one's a bit of a messy one since there's a fair number of champions with shiny armour. That'll be the pain to find.
We can figure things tomorrow if you want, I'm not busy at all.
