Thassilonian Focus (Ex)
Source: Adventurer's Guide, p. 57
The Cyphermage chooses one of the seven schools of Thassilonian magic, as detailed on page 63 (if the Cyphermage is a Thassilonian specialist [see page 63], he must choose the same school of magic for his Thassilonian focus as he chose for his specialization). He gains a +2 insight bonus on all saving throws against spells and spell-like abilities from that school of magic.
