Elminster`s Evasion

This is an enhanced and customized version of the contingency spell of which Elrninster is quite proud; he calls it a "good and true alternative to lichdom." Upon the declared conditions (no more than six simple clauses), the spellcaster's body, complete with his soul or spirit, even if separated from the body, with any of the items held at the time, is snatched through a momentary (1 action) worldwalk portal to the place where the spell was originally cast, even if that place is many planes distant. When casting the evasion spell as a ritual, the worldwalk it uses must also be cast, along with telekinesis to move the body, and two other spells of the caster's choice. All four of these spells must be personally cast and can not come from devices or other spell·casters. The evasion remains in effect until one of the six conditions is met. The material components of this spell are a pint of the caster's blood and a gem of at least 5,000 gp value. Both are consumed in the casting. The caster also loses 1d4 hit points which cannot be healed, until the spell is triggered, at which time they can be recovered by normal or magical means.
Elminster's version uses only five conditions - death, loss of control over his mental faculties, loss of control over his physical body, destruction of both upper limbs or equal physical damage, and uttering the command word "Thaele".  He would usually cast this spell from an extra-dimensional "safehold" (location unknown), to which the evasion would take him when activated. Upon arriving, some sort of magical creature (unseen servant, homunculus, or golem, (Elrninster is deliberately vague) would administer an elixir of health, elixir of life, Keoghtom's ointment, and up to six potions of healing. The two spells to be activated on his arrival were a very carefully worded wish, to restore him to mental and or physical health if necessary, and a sending spell that contacted Elminster's friend The Simbul, mage-queen of Aglarond, saying "I am sorely wounded, if you value my life, come to the safehold quickly". At least that was the situation up until the Spellplague and the events afterward. Since her death, it`s not known whom he would call to restore him or any other modifications he needed to make to the spell.
