Thunderlord's Decree LeBlanc Bug?
I was playing a game yesterday as Cass against a LeBlanc and I noticed that LeBlanc can just cast 2 spells and still trigger Thunderlord's Decree, usually with just Q+R. A friend told me she probably threw in an auto attack to trigger it. So I decided to test it out today in a custom against a Soraka Bot.
I first tested 3 autos just to make sure that works fine (which it does). I then tried Q+R ONLY (no auto attack) and it triggered Thunderlord's. I also tried using her E with a combination of 1 auto attack and also E+Q and Thunderlord's also triggers.
So at this time, I concluded that Thunderlord's triggers off the number instances of damage and not necessarily the number of spells. So I decided to try it on Vayne and her condemn and see if I get the same results. Turns out I still need to auto attack once to trigger Thunderlord's.
I haven't tried it on any other champions so far but it would be interesting to see if this happens on any other champions as it does to LeBlanc. Either way, it's not consistent on every champion and should be looked into.
EDIT: After viewing some replies, I believe the description of Thunderlord's should be changed so it explains instances of damage and not necessarily spells. ALSO I did the Vayne testing again and I realized it is working like the other spells. 1 condemn into wall plus auto triggers auto (I derped on that the first time).
