Within the area of effect, this spell impedes the use of spells of the summoning school and other effects that summon creatures. Any such spells, spell-like abilities, or similar summoning effects used within the area have a percent chance of failure equals 5% × your caster level, to a maximum 75% chance of failure. If the summoning effect already has a percent chance of failure (as is often the case with the summon spell-like ability of outsiders), these percentages stack. This spell does not affect summoners attempting to summon their avatars, but it does affect summoners (as well as yourself) casting other summoning spells.
