The Star Hairclip, as the name suggests, is a golden star-shaped hairclip. Contrary to its name, it appears to be a pair of star clips.
It is a fairly balanced hat that increases Natalie's Magic Attack, MP, Defense, Magic Defense, Evade, and Accuracy by small amounts. It also provides resistance against Magic Attack and Magic Defense debuffs - becoming a complete immunity by Level 5. Additionally, the Star Hairclip boosts the power of Natalie's Lucky Star and Star Shower skills.
