Calls forth winds to greatly increase the caster's movement speed. After the effect ends, the caster's movements will be sluggish for a time.

Swiftness is a level 2 Air/Charms spell which reduces your movement delay.

Effect

Once cast movement delay is reduced by 25%, making it easier to escape combat or pursue fleeing enemies. However, after the speed boost ends, your movement speed will be 50% slower for the same amount of time. For centaurs, and anyone with movement delay 7, the fluctuation is smaller: the increase only brings them to 0.6, a 16.7% bonus, while the penalty slows them by 20%.

Limitations

• This spell stacks with other sources of speed, such as Haste and boots of running.
• Be aware that if you move onto water (without being airborne), your Swiftness is temporarily suppressed.
• Spriggans cannot cast this spell unless under the effect of transformations which restore 1.0 move speed (or slower).
• Due to their stasis, Formicids cannot cast Swiftness.
• Cheibriados dislikes the use of Swiftness -- using it will incur penance.

History

• Swiftness will be a pure Air Magic spell in 0.26.
• Prior to 0.25, Formicids could use Swiftness.
• Prior to 0.14, there was no slowdown after the spell ended, but it penalized stealth and trap detection while active. It also reduced move delay by a flat 0.2 instead of by a percentage.
• Prior to 0.13 this spell couldn't be cast while standing in shallow water.
