The user recovers 1/16th of its max HP each turn. This effect is removed when the user switches. The effect of this move can be passed by Baton Pass.
Aqua Ring is not a move seen frequently in competitive play. It is very rare that a Pokemon would stay in long enough to benefit from this move more than it would from another recovery move, or from simply setting up or attacking. This move may see a little use on some pure stallers in conjunction with other recovery such as from Leftovers—for instance, a Walrein in hail could become even more annoying after having set up with Aqua Ring. Though Aqua Ring may sound useful for a Baton Passing team, given the frequent use of Substitute, frequent switching into entry hazards, and that Vaporeon, a very useful Baton Passer, learns it, Ingrain almost entirely outclasses it in this regard.
Ingrain heals the same amount of HP each turn, but it doesn't allow the user to switch out, whether willingly or forcibly.
