Feat question Heighten Spell

[mechavoc]

How would I use this feat in FG ?

A heightened spell has a higher spell level than normal (up to a maximum of 9th level). Unlike other metamagic feats, Heighten Spell actually increases the effective level of the spell that it modifies. All effects dependent on spell level (such as saving throw DCs and ability to penetrate a lesser globe of invulnerability) are calculated according to the heightened level. The heightened spell is as difficult to prepare and cast as a spell of its effective level.

Drag the spell link from the spells module to the spell level entry in the actions tab one level higher than normal. This will inherit values specific to the spell casting level that the spell description is contained in.
