Call of the lord

As a call that passes through the upper, lower and material planes you call creatures of any kind, less humanoid to come to your aid, choose an unoccupied space up to 30 fts from you and in the chosen place a portal is created where the invoked creature leaves the creature is friendly and loyal to its caster and neutral with allies, but any creature other than it is considered a possible threat until its caster says otherwise.
The summoned creature has a telepathic link with its spellcaster allowing for communication with each other where the language of communication is common.
The challenge level the summoned creatures have is either the caster level or above, and it is only possible to summon a creature in both cases, but if summoned up one level, the creature will do anything to keep its master safe and stay hostile with allies, but he would not immediately attack them unless they stand in the way of an enemy who threatens their master, making them possible targets.
