= Eviolite Eviolite is an item introduced in generation 5. It increases both defenses of a pokemon that is able to evolve. (Phione does not count, as it cannot evolve.) In LU, with the top fully evolved pokemon gone in OU and UU, the pre evolutions have much more potential. Examples are: Tangela Shelgon Metang Scyther Ferroseed Duosion Hippopotas Gurdurr Frillish Roselia Rhydon Natu Magneton Tangela Fraxure Discuss.
