Twinkle

The Twinkle is a Light Pet summoning item that spawns a Life Spirit to follow you around. The Life Spirit is immune to damage from enemies and despawns upon player death. When the player that summoned it is hurt, Life Spirit will periodically create healing energy motes that can be picked up by any player to heal them a small amount of health; however, 10 mana is consumed every time the energy is created. It also provides a small amount of light.

This item can be crafted at a Work Bench with 50 Pixie Dust and 8 Souls of Light.

Trivia

 * The spirit summoned, like the Fairy, is similar to those from the Legend of Zelda series, specifically Tatl from Majora's Mask.
