One of the three improvements for the Shovel Blade the Drop Spark causes a projectile to appear when Shovel Knight swings the Shovel Blade at full health.
The Drop Spark is the subject of the Sparker Feat, which is earned by landing the last hit on a boss with the technique.
Notably the projectile causes Ratsploders to instantly detonate.
The Drop Spark can only be used in Amiibo mode by equipping the special move "Shovel Upgrades".
- Shovel Knight's Drop Spark ability operates similarly to Link's Sword Beam in the majority of the Legend of Zelda games: they both must be at full health to unleash their attack.
