Jonstal's Improved Double Wizardry

This powerful spell enables a caster to unleash two specific spells at once, with the utterance of a single word. Both spells take effect in the same round on the caster (or both on a recipient being), and function normally, except that their durations become 1 round per level of the caster. The two spells must have memorized beforehand by the caster. They are not lost from memory until the improved double wizardry is employed. If either magic is cast by itself, the improved double wizardry vanishes with it.

Material components for the two spells are consumed when this spell is uttered, and must be on the caster's person (but need not be revealed or handled by the caster) or the improved double wizardry will not take effect. Only the caster can unleash the spell.

The only two spells that can be paired by use of a Jonstal's improved double wizardry are fly and non-detection. Despite years of research, the archmage Jonstal has managed to master only one other pair of “combination” spells (see Jonstal's double wizardry). No known being short of the Faerunian lesser divine power Azuth can freely cast any two spells in the same round.
