Carapaca's Assistance

With the materials placed around  the circle at their proper points, you may then summon as many arthropods as the summoner wishes as long as their total difficulty level is less than the summoner's current level and each creature has at least a 1/8 in CR (no CR=0s). The summoner will also need to make a animal handling check on each individual creature summoned that is equal to or higher than their difficulty level +2 in order to gain Carapaca's guidance. With Carapaca's guidance, the arthropods will listen to any verbal or telepathic command given to them by the summoner as long as it does not go against their inherent nature (e.x. jump in a fiery pit of death).
