I don't just mean the ones that restore HP I also mean the ones that raise stats or power moves.
Stat-Boosters: Motor Drive: raises speed when hit with an electric attack(and has immunity to them) Sap Sipper: Raises attack when hit by a grass move(and has immunity to them) Flash Fire: Raises the power of fire attacks when hit by a fire move (and has immunity to them) Storm Drain: draws in all water attacks, and raises special attack when hit by one (and has immunity to them) Lightning Rod: draws in all electric attacks, and raises special attack when hit by one (and has an immunity to them) HP-Boosters: Volt Absorb: immune to electric and heals 1/4th HP when hit by an electric attack Water Absorb: immune to water and heals 1/4th HP when hit by a water attack
