Effect
Equip only to a Machine-Type monster. Once per turn: You can activate this effect; it permanently gains 400 ATK. (This ATK gain remains even if this card leaves the field or the monster becomes unaffected by card effects.) If it battles an opponent's monster, that monster's effect is negated during the Battle Phase only.
The effect "You can increase the equipped monster's ATK by 400" is an effect that activates and creates a Chain Link.
If you activate the effect "You can increase the equipped monster's ATK by 400" during your next turn after having activated it previously, each effect is applied, and the equipped monster's ATK will be increased by a total of 800.
As long as the monster equipped with "Gravity Blaster" remains face-up on the field, the ATK increase from the effect of "Gravity Blaster" continues to be applied. Furthermore, even if "Gravity Blaster" is destroyed after the effect "You can increase the equipped monster's ATK by 400" has been applied, the ATK increase from the effect of "Gravity Blaster" continues to be applied as long as the monster that was equipped with "Gravity Blaster" remains face-up on the field.
