The Onyx Excavator Key is a Pre-Hardmode mount summoning item obtained from the Cavern shrine. When used, it summons an Onyx Excavator which acts similarly to the Basilisk summoned by the Ancient Horn but allows the player to drill through almost all blocks in the game. The Onyx Excavator is capable of moving at a speed of 40 mph horizontally and can jump a single block off the ground. Like the Basilisk, it can charge enemies and deals 25 damage upon contact. This damage can be boosted through summoner bonuses.
While moving, the player's damage reduction is increased by 10%. This is calculated independently from normal DR and is not affected by Calamity's DR soft cap.
The Onyx Excavator can only dig to the sides. It cannot dig vertically.
