Meld of Lolth

Often used by priestesses to link themselves to a powerful drow male before a battle (to control him when necessary), this spell enables the caster to join minds with another creature. The meld allows the caster to see through the other being's eyes and read its thoughts, and communicate telepathically with the linked being.

The caster can act, speak, and cast spells normally without ending this link, and is able (whenever not casting another spell or using any psionic abilities) to dominate the linked being completely, controlling its body regardless of distance (the spell is broken if caster and linked being end up on different planes). The caster can use the linked being as the focus (source of emission) of a currently memorized spell, casting it through the linked being – but this ends the meld instantly.

If the linked being's Intelligence is less than the caster's, it is allowed a saving throw vs. spells once per turn to break the meld. If the linked being is as intelligent as the caster (or more so), and is or becomes (that is when ordered into danger) unwilling to be in the meld, it gets a saving throw vs. spell once every second round to escape.

Whenever the linked being suffers damage, the caster must make a successful saving throw vs. death magic. Failure ends the spell, and the pain-wracked caster suffers 1d6 points of damage. If the linked being dies, the caster must make a successful system shock roll or die instantly (the caster can willingly end a meld 1 round after deciding to do so).
