[GAMEPLAY] Relic Shield Not Losing Stacks
I've only gotten this to happen once, but it was very interesting, and while it would be difficult to abuse, it might™ be significant if people put work into it. I was 
botlane, soulbound with my 
ADC. After we had both been forced out of lane and had come back, I was extremely close to getting a 
stack, so I tried to time last-hitting a minion as soon as the stack arrived. To my surprise, I procced the stack on a melee minion at (probably) the exact frame that the buff updated to having one stack. The proc was real, as both me and my ADC were healed, and afterwards, I still had a stack, which I promptly procced (and this proc was real as well) on the siege minion. I haven't tried to replicate this, as it would be very difficult to time, though using the melee execute would probably help significantly.
Steps to recreate:
- Buy a (not sure if map/champion/nearbychampion/etc are specific)
- Use both initial stacks on minions
- Wait until you are about to recieve a new stack
- Time an attack so that you last hit a minion at the exact instant that your buff updates from zero stacks to one stack.
Effects: You should have procced the stack, with your nearby ally and yourself receiving healing, and your ally getting the gold, but your stack count should not have decreased.
tl;dr - Last-hitting a minion with at the exact instant the buff updates from zero stacks to one stack seems to proc its effects without consuming the new stack.
