Waves of weariness

Waves of weariness was an enchantment spell that could cause a person or creature to either pause in their attack or fall to the ground completely, depending on the target's wisdom or intellect.

Effects
This spell could affect one creature up to 40 yd (36.6 m) away. If the target had sufficient resistance to spells, then this spell failed with no ill effects. Otherwise, creatures of above average intelligence or wisdom were suddenly fatigued enough to cause them to delay their next action, hopefully giving the caster or the caster's allies an advantage. Creatures of below average intelligence or wisdom were overcome with exhaustion and vertigo, causing them to collapse immediately for one minute. After the spell wore off, the target recovered just as quickly.

This spell only affected creatures that normally sleep. Undead and elementals, for example, were immune.

Components
In addition to somatic gestures, this spell required the caster to read aloud from a small book of poetry, such as Translations from Kara-Tur Haiku by Lhaeo of Shadowdale.

History
This spell was published in "Volo's Guide to All Things Magical" and became generally known to the magical community.
