You create a magical field around summoned creatures you control that deflects attacks made against them. The targets gain a deflection bonus to their AC equal to 1 + 1 for every 6 caster levels you possess (maximum +4 deflection bonus at 18th level)
The target immediately becomes addicted to the drug used during the casting of the spell (see drugs and addiction). If the target was ever addicted to the drug at any point in the past, it takes a –4 penalty on its saving throw.
You reduce the target creature's ability to tap into a single energy type (acid, cold, electricity, fire, or sonic) of your choice. This reduces damage of the selected type the creature deals with spells, spell-like abilities, and supernatural abilities by 10 points.
As scale spikes, except that the spikes growing out of the scales have an enhancement bonus on attack and damage rolls equal to +1 for every 4 caster levels (maximum +5). This bonus does not allow the spikes to bypass damage reduction aside from magic.
You disrupt the conjuring energies within a summoned creature, causing it to violently explode. If the target fails its Fortitude save, it is immediately slain and all creatures within 20 feet of the target take 1d4 points of damage per spell level of the summoning spell that conjured the target
You create an extradimensional link between yourself and one summoned creature you control that allows you to switch places. After casting master's escape, you can teleport to your summoned creature's space as a swift action, causing your summoned creature to teleport to your former space
If a creature successfully takes the item targeted by this spell while you are holding, wearing, or wielding it, the creature must attempt a Will save. If the creature fails its save, it becomes fatigued, and it must attempt a new saving throw at the end of its turn every round it does not return the item to you.
All living creatures within the area of effect, including yourself, must immediately attempt a saving throw with a –2 penalty against any and all diseases they have contracted, even if the onset time has not yet elapsed. On a failed saving throw, the affliction has its usual effect. A successful save does not count toward curing the affliction.
As black tentacles, except it creates a Large decapitated snake, which erupts from the ground and grapples a creature you specify within its 5-foot reach. As a standard action, you can command the snake to release its grappled target and direct it to attack a different creature.
