Prerequisite: Charisma 10

Effect: The companion gains the ability to cast a small number of low-level spells. Choose any three spells from the following list: acid splash, detect magic, flare, light, message, ray of frost, read magic, sift, or spark. The construct companion can cast these spells at-will. The caster level for these spells is equal to the companion’s Hit Dice, and the save DC for these spells is equal to 10 + the companion’s Charisma modifier.

Resonance: The companion emits an energy that boosts magic casting. Allies within 30 feet receive a +1 bonus on caster level checks and concentration checks. This bonus increases by +1 at 5th level and every four levels thereafter. This resonance lasts for 1 minute.
