Attribute Booster is a series of Effect Monsters, which debuted in Metal Raiders, and their Link-2 Link Monster counterparts. All of its Main Deck members Level 2 monsters, except for the Level 1 "Milus Radiant". The Equip and Field Spells all increase the ATK and decrease the DEF of their corresponding Attribute.
The Main Deck monsters share the effect "As long as this card remains face-up on the field, increase the ATK of all [same Attribute as its own] monsters by 500 points and decrease the ATK of all [opposite Attribute] monsters by 400 points.".
The Link Monsters are Link 2 and have 1400 ATK, require 2 monsters of the same Attribute to be Link Summoned, have both Bottom-Left and Bottom-Right Link Arrows, and share the effect "All [same Attribute as its own] monsters on the field gain 500 ATK and DEF, also all [opposite Attribute] monsters on the field lose 400 ATK and DEF. If this card is destroyed by battle or card effect: You can target 1 [same Attribute as its own] monster in your GY; add it to your hand. You can only use this effect of [this card's name] once per turn."
