The movement speed of Isaac.
Speed is calculated by a multiplier of current speed, base speed being 1.0. Each starting character has a base speed multiplier and items collected will increase or multiply this value depending on its effect. Speed modifies a constant, so the player can never be immobile.
Unlike other stats, Speed does possess an absolute limit, meaning once Speed hits a certain value it cannot be raised any further.
