Mage Knight: Machination
Prerequisite: Magus level 4, Technomantic Staff OR Golem Familiar
You can alter a burst, emanation, line, or spread shaped cantrip to increase its area. Any numeric measurements of the cantrip’s area increase by 100%. Cantrips that do not have an area of one of these four sorts are not affected by this feat.
If the magus casting the widened cantrip is bonded with a technomantic staff, the widened cantrip takes a -3 caster level penalty (apply this penalty AFTER applying this feat’s effects), as if the staff had granted a caster level bonus on a cantrip in the round prior to the one during which the widened cantrip is cast.
If the magus casting the widened cantrip is bonded with a golem familiar, the golem takes a -3 penalty on all attacks, special attacks requiring a roll, saving throws, and skill checks from the end of the round during which the widened cantrip is cast until the beginning of the magus’ next turn.
