The geyser kb prerequisites are ridiculous. You have to miss 3 times for it to come out. Its never worth the risk because its 28 start up. Unless Cetrion has a stagger that leaves the opponent stunned long enough to whiff geyser, and then retreat to block any punishes, its hard to believe the kb is easy to pull off. Its a good kb to, it bounces the opponent. The only time I get it to come out is during the "finish them" part, where I'm free to whiff geyser 3x and then kb them.
