|The user attacks everything around it with a ground-shaking quake. Its power varies.|
Magnitude's power varies based on a randomly selected "magnitude" value ranging from 4 to 10, with 4 having the least power and 10 having the greatest.
Magnitude can hit a Pokémon during the semi-invulnerable turn of Dig, and if it does, it will have its power doubled for that Pokémon.
Power varies as follows:
If Magnitude hits a Pokémon during the semi-invulnerable turn of Dig, instead of doubling power, damage is technically doubled instead now, resulting in virtually the same effect.
If Grassy Terrain is in effect, Magnitude deals only half the usual damage.
