Casting Speed

Overview
Cast speed may be increased or decreased with certain buffs or debuffs that affect casting speed and have the 'casting speed trait'

Casting speed increases are additive and range from -100% to +100%. Each % of casting speed gained increases the casting speed, making a spell cast faster. Each % of negative casting speed gained decreases the casting speed, make a spell cast slower.

Casting Speed and Instant Casts
Casting speed does not affect instant casts directly; rather it reduces the global cooldown, allowing faster use of instant cast abilities.

Casting speed and Casts
Normal casts gain a linear increase or decrease that corresponds with the casting speed increase or reduction. A spell that were to have a 10 second cast time would have its cast time reduced to 5 seconds at +50% casting speed increase and increased to 15 seconds at -50% casting speed reduction.

At +100% cast speed, the user will gain the Fast Casting effect. See the Fast Casting page for more information about fasting casting.

Casting speed and Channels
Channeled casts, similar to normal casts, gain a linear increase and decrease that corresponds with the casting speed increase or reduction.

At +100% cast speed, the user will gain the Fast Casting effect. See the Fast Casting page for more information about fasting casting.

Casting speed and Global Cooldowns
Similar to casting, global cooldowns receive linear increase and decrease that corresponds with the casting speed increase or reduction. However, a Global Cooldown cannot be reduced below 0.4 seconds or increased beyond 2.5 seconds.

+100% Casting Speed
At +100% casting speed the user gains the Fast Casting casting effect and all cast abilities are treated as instant cast abilities. See the Fast Casting page for more information.

-100% Casting Speed
At +100% casting speed the user gains the Silence effect and can no longer use abilities. See the Silence page for more information.
