Speed

is one of the eleven core player statistics. It is a measure of the walking and running speed of the player expressed as a percentage of the original speed. Interestingly, speed will not apply while jumping.

Any item that increases speed by a base value (such as ) can be thought of as an increase of the base speed by that much percentage.

It is capped at under normal circumstances, but this cap can be increased to. When Mayor Technoblade is elected, the speed cap is removed, allowing players to achieve speed higher than 600%. High speed is very hard to reach under normal circumstances. Most methods of reaching speed require the Rogue Sword, or armor such as the Obsidian Chestplate, Farmer Boots, and Young Dragon Armor, or buffs.

Increasing Base Speed
Players have a base of  by default. It can be increased by:
 * Turning in Fairy Souls to Tia the Fairy
 * Leveling Wolf Slayer
 * Holding more Accessories

Increasing Bonus Speed
There are several ways to gain additional bonus, which last for various amounts of time.

Increasing Maximum Speed
Players have a maximum of  by default. It can be increased by:
 * Young Dragon Armor's Full Set ability
 * A Black Cat Pet's first ability
 * One of the Resistance Leader's perks, Unlimited Speed, halved all speed above 400% and removed the maximum speed cap.

Note that both item abilities apply and the player's maximum speed can be extended to, but appears not to with the popular mod SkyBlock Addons made by Biscuit, as it only supports up to speed. Inspecting the SkyBlock Menu's profile will correctly display the speed.

The Unlimited Speed perk proved to be broken limiting speed at despite displaying the speed stat without the cap.

Decreasing
A mob's speed stat can be worsened in a handful of ways. A Slowness Potion decreases speed by the same intervals as speed potions. The Venomous Potion decreases speed by per level up to.

Players may use Rancher's Boots to cap their speed at a lower value, used notably to farm efficiently without skipping crops from too much speed outpacing the block breaking speed.

Achieving Maximum Speed

 * The Player starts with base  and a  cap of.
 * A Black Cat Pet holding a Spooky Cupcake provides  ( from Hunter Ability,  from Pet Stats,  from Spooky Cupcake) and raises the  cap by.
 * A set of Recombobulated Young Dragon Armor with  boots provides   or  if under   ( from armor stats,  from   reforge,  from, and  from Young Blood if over  ), and raises the  cap by.
 * A held maxed Yeti Rod provides.
 * 200 Fairy Souls provide.
 * Level 8 Wolf Slayer provides.
 * The Potato-Style Century Cake provides.
 * The Tier V Beacon Buff provides.
 * Accessories provide  without reforges ( from Bat Artifact,  from Frozen Chicken,  from Wolf Paw,  from Pig's Foot,  from Cheetah Talisman,  from Speed Artifact, and  from Potato Talisman)

Combined, this raises the cap to, and gives a  of  obtained from  (Base) +  (Black Cat Pet) +  (Young Dragon Armor above  ) +  (Yeti Rod) +  (Fairy Souls) +  (Wolf Slayer) +  (Century Cake) +  (Beacon) +  (Accessories). With a few accessories reforged to or enrichments, it is possible to achieve the  cap of.

There are also some more inconsistent methods of raising speed which can be added such as giving a percentage buff to all stats depending on the amount of nearby players as well as island affinity talismans (such as the Village Affinity Talisman), the private island Beacon buff, and potions. If one were to aim to achieve the highest theoretical regardless of the cap, it would be possible to go above  (Credit: PotatoAim [Note: There are a few errors in the estimations but it gives a good idea of the magnitude of speed that can be reached]). This is without factoring the Rogue Sword which given unlimited mana, can theoretically let the player reach near infinite.

Using all of the accessories from this incomplete list (other than accessories that have a higher tier) with a Vivid reforge gives approximately.

Speed in B/s
Movement speed in blocks per second can be easily calculated using this formula:

$$Movement Speed = Base Speed * Speed Modifier$$ Base Speed - amount of movement speed coded into Minecraft. Base Speed values for different actions are following: Speed Modifier - your Speed stat value. Percent value must be converted to decimal (e.x. 230% = 2.3).

Example

 * Information
 * Action: Sprinting
 * Speed value: 207%
 * Calculation

$$5.6 * 2.07 = 11.592 B/s$$

Trivia

 * There used to be a bug where the speed buff from the Aspect of the End never ran out on the player's island. This allowed for the player to easily achieve 400% speed. This was patched in version 0.7.
 * Riding on a Level 1 Skeleton Horse Pet is equivalent to walking with 200% speed (8.62 B/s).
 * Riding on a Level 100 Skeleton Horse Pet is equivalent to walking with 500% speed (21.55 B/s).
