Toothed Tentacle - Phaerimm

This spell creates a shadowy, insubstantial “tentacle" or flexible arm extending out from the caster to the limits of spell range. This weightless, retractile limb ends in a cluster of long-toothed, snapping mouths, 1d4+2 in number (round roll up, to an even sum).

These mouths are solid and very real, and bite, slash, and savage foes. They can be attacked by up to three enemies at once, but can only strike at more than one target (up to the maximum of three) if the targets are grouped around the cluster of mouths to engage them.

The mouths are AC 5 and have 14 hit points each. They bite for 2d4 points of damage each, every round. When a mouth is “killed," it fades away, taking a second mouth with it; if this leaves no mouths, the spell is ended.

Only the mouths and their cluster of eel like “necks" can be attacked; the shadowy tentacle cannot be hit or harmed (except by application of a dispel magic, which ends the spell instantly). The tentacle can be passed through freely, and even be intersected by solid barriers and objects (though the caster must be able to see foes, to use the mouths against them), without harm to the caster or the spell.

The caster gains no benefit of hit points, vitality, blood-food, or the like through the tentacle. The caster must concentrate on directing the tentacle; if he is killed, loses consciousness, or undertakes the study or casting of another spell, the tentacle fades away and this spell is ended.

The material components are a hair and three teeth (they need not all be from the same corpse or species).
