Arcane Conduit

You have developed a synaptic link between yourself and your companion, working in tandem to achieve arcane mastery. You gain the following benefit:

On your turn, as a bonus action you can create a link between yourself and a bonded companion within 100 feet. Until the end of your next turn, the next spell you would cast is cast by your companion instead. Use your companion’s location to determine range and visibility of targets. Your companion automatically provides all verbal, somatic and material components without a gold cost. If the spell uses an attack roll, spell saving throw, or similar requirement, it uses your modifiers.
