The Speed Droplet is a tier 3 trinket that, when equipped, increases the player's speed by 10%. It has a 1/12 chance of being stolen from aphids via the Rascal Rogue Mutation or the Sticky Fingers trinket.
Due to the Aphid's inherent lack of health, using weaker weapons or simply your fists are recommended to maximize chances of getting both steals from the Sticky Fingers or Rascal Rogue mutation. Aphids cannot live more than a single hit, even with basic fists however using a Healbasa can allow for more attempts to steal from each Aphid. A useful strategy to maximise chances is to trap an aphid, punch it once then drop a healbasa and repeat until an item is stolen.
