Chaotic Bond

Choose a creature within 60 feet of you. You create a magical bond between you and the target that lasts until the spell ends. While the bond is active, the magic flow between you. Every time you or your bonded ally cast a spell, the caster can choose to cast its spell as if it were the other : You can cast spells as if you were your ally, using its senses and its position to determine the targets of the spells; and your ally can cast spells as if it were you, using your own senses and position. The caster still uses its own spellcasting modifier, concentration and spell save DC when the effects of a spell require them.

For instance, if you cast a spell with a range of self, you can choose that it targets your bonded ally instead; if your bonded ally casts a spell with a range of touch, it can choose a target in your own range of touch instead of its own; or if you cast a spell with a range of 30 feet, you can choose a target that is either within 30 feet of you, or within 30 feet of your bonded ally.
