Slayer's Earring

The Slayer Earring, also translated as "Slayer's Earring", is an accessory found in Kingdom Hearts II, Kingdom Hearts II Final Mix, and Kingdom Hearts III.

Design
The Slayer Earring is a silver earring. Its lower half is comprised of a long, thin, blunt spike with four extensions on its sides; two small, curled extensions and two longer, blunt spikes that angle upward sharply. There is a small, circular, cyan and pink gem set in the upper half of the main spike. A serpentine dragon with its wings raised is perched on the top of the earring.

Kingdom Hearts II
The Slayer Earring can be synthesized through Free Development once twenty types of materials are obtained. It is a rank B synthesis item that provides 24 EXP, and is an upgrade of the Mage Earring recipe.
