The Blessed Dart as seen in the Special Items menu.
Blessed Dart is a Special Item in Bloons Monkey City. It is obtained randomly inside chests. Once obtained, it permanently increases the pierce of all Dart Monkeys by 20%, regardless of whether its projectiles are darts or not. [NOTE: 20% extra pierce experiment is currently being tested.]
It is also an epic dart weapon in Bloons Adventure Time TD.
