Semipermanency

This spell affects the duration of certain other spells, making the duration significantly longer. To the casual observer, the effects may seem permanent, but in fact the duration is limited to some number of years, based on the caster's Level: roll 1d20 and subtract the result from the caster's level to yield the duration of the spell in years. If the result is 0 or less, roll 1d12 instead to find the spell's duration in months. The DM should roll these duration dice and keep the results secret from the caster. Casting this spell has no effect on the caster's Constitution score.

The personal spells upon which a semipermanency spell is known to be effective are the same as those listed for the more powerful permanency spell. The wizard casts the desired spell upon himself, then follows with the semi-permanency spell. This application of semipermanency can be dispelled only by a wizard of greater level than the spellcaster was when he cast the spell. Affected spells included:

* comprehend languages * detect evil * detect invisibility * detect magic * infravision * protection from cantrips * protection from evil * protection from normal missiles * read magic * tongues * unseen servant

The semipermanency spell can be used to lengthen the duration of some spells affecting creatures, objects, or areas, as follows:

* enlarge * fear * gust of wind * invisibility * magic mouth * prismatic sphere * stinking cloud * wall of fire * wall of force * web

Finally, the following spells can be cast upon objects or areas only and rendered semipermanent:

* alarm * audible glamer * dancing lights * solid fog * wall of fire * distance distortion * teleport

In applications other than those directed on the caster, this spell can be dispelled normally to negate its effects.

The DM may allow other selected spells to be made semipermanent. The selected spell must be researched anew, costing as much and taking as long as its original research. The DM must decide whether a specific spell can be made semipermanent. The semipermanency spell cannot be used in the process of manufacturing magical items.

The material components are a drop of dwarf's blood and a tiny metal anvil (50 gp minimum).
