This spell is cast alongside another spell, extending that spell's power in several ways.
The caster can add this spell to the casting of another spell, increasing the casting time of the spell to be affected by 2 segments.
The affected spell must be less than 6th level or the magic is wasted (the extension does not function).
If the affected spell is less than 4th level, the duration is doubled (for any duration longer than instantaneous and less than permanent or permanent until discharged).
Otherwise, the affected spell gains +50% to duration (for any duration longer than instantaneous and less than permanent or permanent until discharged).
The affected spell is considered to be a 6th level spell (with regards to spell level effects but not actual spell effects).
The caster level of the affected spell is increased by 2 (before considering the increase in duration).
Limitations
Only spells (incantations) can be affected by extension spells. Spell-like abilities, innate abilities, or magic items powers (invocations, even spells on scrolls) cannot be affected by this spell.
The caster of extension must be the caster of the affected spell.
If the affected spell does not have a verbal component, this spell adds a verbal component to the casting.
Metamagic spells only affect mage spells even if the caster is multi-classed.
A metamagic spell cannot be used to affect another metamagic spell or used on a spell combined with another metamagic spell.
