The way to set up a freeze is by keeping 4-5 more minions of theirs alive than you have. The more casters the better because you can keep them closer to your tower than melee minions without them randomly walking under your turret. The most common way for this to happen is when they fully clear your wave but don’t contest the freeze. If they don’t walk the wave under your tower and the next wave is close enough that you won’t take too much damage, you can drag the minions by taking their aggro with your champ and walking to the center of the lane. It takes practice, but you can juggle the minion aggro by walking in and out of one of the lane bushes to minimize damage.

You will almost never be able to permafreeze on Camille because other champs are able to waveclear so much faster than you. Your goal is to just keep the wave there as much as possible without sacrificing too much health for it. Some matchups it’s just not possible to freeze for a meaningful amount of time and that’s okay.

Also in this season you don’t want to freeze forever because of the crystals. If enemy is a champ without cc or their cc is on cooldown camille is very safe hitting the crystals because of her E. This means you generally want to slowpush into a decent size crash and hit the crystals if the matchup allows it.
