Safeguard Details + Use
|Safeguard Move Details|
Safeguard is a support move. When used in battle, Safeguard protects your party’s Pokémon against status effects:
Safeguard also guards the party members against Confusion. Safeguard’s effect lasts for five turns, and cannot be extended.
On the other hand, Safeguard does not prevent self-inflicted status conditions:
- Status conditions caused by held items: Berries (Confusion), Toxic Orb (Poison) and Flame Orb (Burn).
- Status conditions caused by the secondary effect of a move: Rest (Sleep), Trash, Outrage and Petal Dance (Confusion).
When used with a Normalium Z, Safeguard turns into Z-Safeguard. Along with Safeguard’s basic effect, Z-Safeguard will also raise the user’s Speed stat by one stage.
Defog will remove Safeguard’s effect. Pokémon with the Infiltrator ability will also bypass Safeguard’s effect.
In Generation VII, Safeguard has been largely replaced by a new move, Misty Terrain.
Misty Terrain will also protect the party members against status effects. Unlike Safeguard, Misty Terrain can be instantly set up by the ability Misty Surge.
Safeguard does have some small advantages over Misty Terrain. Unlike Misty Terrain, Safeguard will also protect non-grounded Pokémon (Flying types and Pokémon with Levitate). Safeguard also prevents Confusion, while Misty Terrain does not.
In competitive play, Safeguard only appears in Double battles. Even then, it’s not a very popular choice.
In the main story, Safeguard won’t have much use either. Since it requires a full turn to set up, Safeguard isn’t very practical. Additionally, you won’t have too much trouble dealing with status effects in the main story.
