Once you cast this spell both of the targets acquire an almost instinctual insight into the other's minds, giving them the following benefits.

This spell's range is a 30 feet radius centred around yourself, you and one other willing creature both gain +2 to attack rolls for weapons and spells while the two of you are within 30 feet of each other, if either of you moves outside of that 30 feet radius this spell ends, both creatures affected by this spell are magically made aware of the range limitation.

If you cast this spell without any other willing creatures the casting is wasted and you waste a spell slot.
