Dynamo Stem Cells

The Dynamo Stem Cells is a post-Moon Lord, Expert Mode-exclusive accessory that is obtained from the Treasure Bag dropped by The Dragonfolly. It grants the player 15% increased movement speed and a 20% chance for ranged weapons to release miniature swarmers when fired. The swarmers deal more damage the higher the weapon's use time, up to a maximum of 70% of the weapon's base damage for weapons with a use time of 10.5 or higher. The swarmers are softcapped at 1000 damage.

Trivia

 * In real life, stem cells are used in the process of cloning animals due to their ability to transform into other types of body cells.
