Draincone - Phaerimm

This spell is an improved version of dweomer vortex, in which the drained spell energy does benefit the caster. The spell creates a shimmering conical field in midair, its small end towards the caster, and its circular open end of 4-foot-radius size. The draincone moves in response to the wielder's thought, floating freely through the air at a rate per round up to 6, so long as it does not strike solid barriers (which it doesn't affect, but can't pass through). If it encounters magical areas of effect, and waiting but not yet-triggered magical traps), it whirls, flashes, and "drinks" them.

Draincones cannot affect antimagic shells, or any prismatic spell of 5th level or higher. They have no effect on astral silver cords. They destroy, and are destroyed by, globes of invulnerability and lesser magical barriers upon contact.

A draincone is not ended or affected by its wizard casting other spells, or wielding magical items; it ignores all magic caused by its caster. A dispel magic spell collapses it while it absorbs the dispel magic spell.

A draincone can drain up to 12 spell levels: It can destroy twelve 1st-level spells, or any combination of spells up to a total of 12 spell levels, before vanishing in a harmless, spectacular whirl of winking lights. A spell that exceeds the limits of the cone is destroyed as it collapses.

When a draincone collapses, its caster receives all of the spell levels it has absorbed, to a maximum of 12, as energy that must be immediately used to "boost" a single existing memorized spell. The spell is augmented so that it will do damage, and take effect, as if cast by a wizard of 12 (or however many spell levels were drained) levels higher than the caster. If the caster has no spells memorized, or none that can be augmented in this way, the energy fades, and its benefit is lost.

Notes: Restricted to Phaerimm; common.
