The Book of Skulls attacking Target Dummies and a Skeleton. Note how the projectiles home in on enemies and explode on impact with blocks.

The Book of Skulls is a pre-Hardmode spell book that has a 36/343 (10.5%) / 1/3 (33.33%) chance of being dropped by Skeletron. When used, it fires slow-moving skull projectiles which home in on enemies, can pierce twice before dissipating on the third hit, cannot pass through blocks, and emit a fair amount of light.

Its best modifier is Mythical.

Notes

  • The skulls home in on enemies that are within 18.75 tiles of them, and they continue chasing their target as long as it is no more than 62.5 tiles away.[1]
    • After acquiring a target, the skulls cannot target another enemy until their current target dies or despawns.
  • The skulls have a top speed of 18 mph.
  • The skulls apply 10 ticks[2] of global invincibility frames upon hit.

History

  • Desktop 1.4.0.1:
    • Skulls now home in on enemies. Previously, they would partially turn towards the closest player (including the caster) briefly after being fired, regardless of the presence of enemies and whether or not PvP is enabled. They would not turn if the nearest player was directly behind them, and they would also turn around if the caster pressed any movement keys.
    • Sell price increased from 1 GC to 1 GC50 SC.
    • Internal projectile ID changed from 270 to 837.
  • Desktop 1.3.0.1:
    • Damage increased from 28 to 29.
    • Mana cost decreased from 22 to 18.
    • Velocity decreased from 4 to 3.5.
  • Desktop 1.2.3:
    • Damage decreased from 35 to 28.
    • Mana cost increased from 12 to 22.
    • Knockback decreased from 6 to 3.5.
    • Use time increased from 25 to 26.
    • Pierce decreased from 3 to 2 (now dissipates on third hit).
