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. “JUST WALK OUT you can leave!!! work social thing movies home class dentist clothes shoppi too fancy weed store cops if your quick friend ships IF IT SUCKS...

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 does stack 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 ineffective.
• Because player movement delay is capped at 0.6, spriggans normally receive no benefit from this spell (and cannot cast it) and centaurs only receive a 1 point bonus. If your spriggan or centaur is moving slowly for some reason, however, Swiftness will function correctly.
• Cheibriados dislikes the use of Swiftness -- using it will incur penance.

History

Prior to 0.14, there was no slow down 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 giving a percentage bonus.

Prior to 0.13 this spell couldn't be cast while standing in shallow water.
