- Aqua Prison acts as a knockup for the purpose of Yasuo's Last Breath.
- It seems to take ~.875 seconds from cast to land (there's wind-up before the bubble is launched) regardless of distance. The AoE has a radius of ~162, making it impossible to escape only if an enemy is at 185 movement speed or less (325 movement speed slowed by 43% would put an enemy within this). This means that cc may be necessary to ensure that this CC lands. Max rank Tidecaller's blessing with 160AP could reach this slow value (though few enemies would likely have 325 movement speed by that time)
