Decastave

Decastave was an evocation spell that converted a small piece of wood into a 10-ft-long (just over 3 m) force-staff that could be used as a magic weapon.

Effects
The magical pole was of fixed length, 2 in (5 cm) in diameter, and rigidly inflexible. It could be wielded like a staff and could damage creatures immune to non-magical weapons. The decastave could be dissipated in a few ways:
 * The wizard let go of it intentionally or accidentally.
 * It was pulled from the wizard's grasp by one or more opponents exerting sufficient strength in a united effort.
 * It was cleaved by metal.
 * The spell's duration was exceeded.

Once per casting of this spell, the wizard could elect to drain a small amount of health upon a successful hit. The health was transferred to the wizard similar to a vampiric touch but could not increase health beyond normal capacity.

Components
This spell required verbal and somatic components, and a small piece of wood that was consumed by the casting.

History
This spell was generally known around Faerûn, once it had been published in Volo's Guide to All Things Magical.
