Arcbond

Until the spell ends at the end of your next turn, when a spell is cast that targets only the target creature and doesn't have a range of self, that spell is copied and cast from the targets position. Any creature within 10 ft of the target must make a dexterity saving throw or succumb to the spells effects as well. If a second target fails their saving throw, all creatures within 10 ft of that target that haven't made a saving throw yet also make a saving throw or fall to the spells effects. This effect continues until it hits a number of creatures equal to your wizarding level. 

If you use twinning magic on this spell, each of the creatures keeps reflecting any spell cast until either one succeeds on a dex saving throw, reflecting the spell each time.

At Higher Levels. When you cast this spell at higher levels, increase the 10ft range around the target by 5 ft for each level beyond the first.
