This feat enables you to have an even more pronounced knack with the spells
of a chosen school of magic. You select the school at the time you train
this feat. Then, when you cast a spell from within that school, it becomes
even more difficult for the target to save against your spell.
The trainer in question must be a member of the specific school you wish to
focus upon.
You may train this feat multiple times, each time for a different school of
magic.
This feat requires that you already posses the Spell Focus feat, in the same
school of magic.
* To train this feat, use the format train 'greater spell focus' <school of
magic>.
