Slow

This article is about the debuff. For the modifier, see Modifiers § Common.

Slow is a debuff that halves the player's horizontal movement speed. It has a chance to be inflicted by direct contact from a Pixie, Wraith, Mummies or Rusty Armored Bones. The beams fired by Necromancers also have a chance to cause this debuff. Equipping the Fast Clock, The Plan, the Ankh Charm, or the Ankh Shield makes the player immune to the debuff.

If the player has any boots that increase movement speed, such as the Frostspark Boots, it will take much longer to accelerate, but the player can still move at the maximum speed allowed by the boots.
If the player has nothing equipped that affects movement speed, they will move at the same speed even when the debuff is active.
If the player is afflicted by the debuff and uses the sandstorm jump via Sandstorm in a Bottle, Sandstorm in a Balloon, or the Bundle of Balloons, they will spin much faster than normal during the ascent.
