Skeletron drop and ricocheting flaming skulls
The Book of Skulls drops from Skeletron with a 10.5% rate in Classic mode or 33.3% from his Treasure Bag in Expert and Master mode. It expends 18 mana per cast at Slow casting speed (32 use time), conjuring burning skull projectiles dealing 29 base magic damage with 3.5 knockback. Skulls pierce up to three enemies and bounce off solid tiles, tracking slowly toward nearby targets.
Wall of Flesh demolition, mana economy, and reforging
Piercing capability and slow flight speed allow individual skulls to impact boss hitboxes multiple times, making it devastating against the Wall of Flesh. High mana consumption requires drinking mana potions or maintaining Mana Regeneration buffs during prolonged boss fights. Mythical is the optimal modifier, lowering mana drain while boosting damage, velocity, and critical strike chance.
Trivia
- The burning skulls launched by the tome resemble miniature variants of Skeletron's phase-two projectiles.
- Because skulls bounce off solid blocks, they can form effective defensive traps in narrow arenas.
