The X Of Y / Terraria

Once you start up Terraria, it's impossible to miss something following the naming scheme of The X of Y. This reoccurs constantly throughout the game, used as the name of enemies and items alike.

Enemies

• The first boss^note progression-wise is the Eye of Cthulhu.
  • For the first phase of it's fight, the eye occasionally summons three to four Servants of Cthulhu, keeping with the trope.
• Sometimes an Eater of Souls will float over to bite you before you even know the Corruption biome is there. This the only one that is an average Mook, and not a boss or its summons.
• Continues with both of the second-tier bosses. The Eater of Worlds for the Corruption and The Brain of Cthulhu in the Crimson.
• The turning point for Hardmode, the Wall of Flesh.^note Or as the Cyborg NPC refers to it, "The Wall of [Guide's Name]".
• Like the Eye, the old-gen/mobile/3DS-exclusive Ocram has servants of his own.
• Journey's End introduces a new superboss called The Empress of Light.
• The Moon Lord's summons, the True Eyes of Cthulhu.

Weapons and Tools

• The Ball O' Hurt.
• The Blade of Grass, a poison-laden broadsword made of plant spores and hornet stingers.
• The Book of Skulls.
• The Brand of the Inferno.
• The Dao of Pow.
• The Eye of Cthulhu (not to be confused with the boss of the same name, this one's a yo-yo).
• The Fisher of Souls, a demonite fishing rod named after the above-mentioned Eaters of Souls.
• The Flower of Fire and the Flower of Ice respectively.
• The Rod of Discord/Harmony, a rare staff that allows you to teleport under cursor point.
• The Scourge of the Corruptor, a staff that spits tiny Eaters of Souls to bounce of the walls and ravage foes.
