Trinity force procs on hit or AA?
So i was playing a game just now and the enemy fiora did 1k damage to me with he Q i questioned it because 500-600 i could understand but 1k+ i didn't get it. so i asked how and they all said tri force i argued that tri force does not proc on that since its not an Enhanced AA but they were insisting that it is proc on hit. i have read the tooltip on tri force over and over and it clearly states On basic attack. and i know what you are all going to say you can AA really fast right after using Q but that doesn't contribute to the Q, thats it's own auto attack so it wouldnt count as Q damage.
Soooo whats the deal with this is it proc on hit or proc on basic attack like the tooltip says?
