==Tips==
*The Collection Page notes that speed is especially important for King Bible, Runetracer, and Bone. This is because the faster the projectiles move, the further they will be able to spin (King Bible) or travel (Runetracer and Bone).
*Speed increases the speed of the bombarding circle of Peachone, Ebony Wings, and Vandalier.
*Speed increases the speed of La Borra's pools, and the speed at which they grow.
*Speed increases the distance that Cross flies before moving in the opposite direction.
*Bracer may be detrimental to weapons that ignore duration and pierce infinitely, such as the Death Spiral or Hellfire. The slow speed of these weapons allow them to pass over more enemies before flying offscreen.
