Sparklers are enemies that support Aquagoth in the fight with it.
Sparklers are invincible and untargetable, so the player has no choice but to focus on Aquagoth. The Sparklers move in erratic patterns over the ground, making it difficult to anticipate their movements and avoid them. Fortunately they do not deal too much damage.
As the player cannot kill Sparklers, they cannot receive any rewards for doing so.
