I've been around the forums, and have heard a good deal on these things called locks. There seem to be multiple ones, but I can't pinpoint a discussion that actually gives info on them, sooo, I'm starting my own.
1: Venom lock. Has something to do with stopping venoms or something, right? How do you like, set up something like this?
2: Rift lock. I didn't even know this was really a thing or possible, if what I'm guessing is true. It's on something with closing of your opponents rift or something?
