Speed boost

A character's movement speed can be increased through the use of various skills, and occasionally by environmental effects or consumable items. Speed boosts can be stacked, but movement rate is capped at 33% faster than normal. The skills Burning Speed, Pious Haste, Junundu Tunnel and Dash break this rule, allowing a character to move faster than the 33% cap.

Speed boosts can be thought of as the opposite of snares. A skill that causes a speed boost is often referred to as an IMS, short for "increased movement speed" (similar to IAS for attack speed).

General overview of speed boosts

 * Stances. Many stances provide a personal speed boost.


 * Shouts. Some shouts augment the movement rate of allies.


 * Pet skills. Speed boosting skills in the beast mastery line can augment the movement rate of a pet, or both the pet and its master.


 * Enchantment spells. A few enchantments provide a personal speed boost for the caster. Windborne Speed can also be cast on teammates.


 * Hex spells. The oddball skill Shameful Fear gives its victim a speed boost.


 * Environmental effects. In Alliance Battles, players that enter the range of an Attack control point that their team controls will receive a movement rate buff from Battle Cry.


 * Consumable items. Essence of Celerity and some sweets (via the Sugar Rush or Sugar Jolt enchantment spells) provide a speed boost to characters while in PvE (either in missions/explorable areas or towns/outposts), depending on which consumable is used.

PvP

 * Tactical movement, e.g. ganking, kiting, or returning from an overextended position. For example, Monks will use Dark Escape to escape and reduce damage while they do so.
 * Counter-tactics: e.g. to catch-up to kiting enemies.


 * Specialized uses


 * Flag running in Guild battles
 * Relic running in Heroes' Ascent, particularly "Make Haste!".

PvE

 * Runners use speed boosts to escape aggro.
 * Flag running: helps complete quest objectives during certain missions by moving bundles quickly.
 * Tactical movement, e.g. kiting and maneuvering.
 * In Hard mode, foes move 33-50% faster than normal.
