For drops see. It also drops Runes which are used in crafting.

Spawn
The Rune Ghost is summoned using a. The Rune drops from Sneaking Ghosts in the Hardmode Dungeon.

Behavior

 * The Rune Ghost flies to 1 out of 6 positions around the player and then picks 1 out of 4 runes to summon; when below 50% health it will summon two runes at once.
 * The red rune fires circular bursts of lasers, with the orientation of the burst changing with each shot. The trajectories are marked in advance by crosshairs.
 * The green rune causes leech runes to be summoned near the player, once fully summoned they will fly towards the position of the player and upon hitting the player they will heal the boss for an amount equal to 40 / times the damage dealt.
 * The cyan rune causes 4 ice runes to be summoned which orbit the player, after a while they will freeze and charge towards the center of the ring, they will freeze the player on contact.
 * The purple rune causes 3 pursuit runes to be summoned, which are homing projectiles that drastically accelerate after a brief delay.

Tips

 * The aggro runes are very easy to dodge as long as you keep moving.
 * The player should avoid running too fast when being circled by ice runes as they can freeze quite abruptly.
 * The player shouldn't move in a straight line when dodging pursuit runes as they move very fast but have low turn speed, the player should move toward a spot perpendicular to their velocity.

Trivia

 * Unlike other boss summoning items the Summoning Rune can be used when a Rune Ghost is already active, making the player able to summon more than one Rune Ghost.
