The wielder will not receive any damage from Ground-type moves. The wielder will also not be affected by Spikes, Toxic Spikes, and can switch out of a Pokemon with Arena Trap. It also receives no damage from the move Sky Drop. These immunities are lost while under the effects of Gravity or Ingrain, or while holding an Iron Ball. Roost does not take away the effects of Levitate.
Levitate is one of the most useful abilities in the game because it gives full immunity to Ground-type moves, some of the most common attacks in the game, and to Spikes, allowing a Pokemon with Levitate to laugh in the face of almost all entry hazards. There are a number of notable Pokemon that benefit from this ability, as otherwise they would have a weakness to Ground-type attacks, such as Gengar and Rotom-W. Levitate is a great ability on almost any Pokemon. The one exception to this rule is Rotom-S.
