Eldritch Caster (Sp)

Prerequisite: Charisma 11, Level 4

Effect: The companion gains the ability to cast a small number of spells. Choose any spell from the following list: break, burning hands, corrosive touch, feather fall, grease, magic missile, obscuring mist, shocking grasp, stunning barrier, or thunderstomp. The construct companion can cast this spell once per day. For every three vanguard levels past 4th, the construct can choose an additional spell to cast once each day. It can also choose a spell it already knows to gain an additional casting of that spell each day. The caster level for these spells is equal to the companion’s Hit Dice, and the save DC for these spells is equal to 11 + the companion’s Charisma modifier.

Resonance: The companion’s magical expertise resonates to allies, making them more able to resist magic. All allies within 30 feet of the companion gain a +1 insight bonus on saving throws against spells and spell-like abilities. This bonus increases by +1 at 10th and 16th levels. The resonance lasts for 1 minute.
