In EBF4 it is a pair of hairclips resembling a pair of green leaves, although it is unclear if these are real or fake. When equipped with the Leaf Clip, the wearer's hair is styled into a pair of ringlets that hang from the sides of their head. It is one of two hats available at the start of the game, along with the Yellow Bauble. In EBF5 the Leafy Hairclip is a hair circlet with a small bunch of green leafs on both the right and left sides.
Its defensive stats remain the same but it now grants bonuses to both Attack and Magic Attack. It can randomly summon the Leaf Wraith between turns, and also gives the Bless status to the wearer when Defending. While it kept its Poison/Virus and Bio resistance, its Fire weakness got changed to Earth resistance instead.
Note: Before the v2 update, had a -30% Fire weakness instead of resisting Poison/Virus, gave Bless between turns (2x strength and 15% modifier) instead of on Defend, and cast Leaf Blade (unlocked at level 4) instead of summoning the Leaf Wraith.
