Your character begins weaving a deliberately over-bright, unstable spell matrix. The spell has no effect on creatures that ignore it, but it looks like the opening movements of a dangerous high-level spell.

When you cast this spell, each creature that can perceive the casting and could attempt a counterspell may immediately make a Knowledge (Arcana) check against DC 20 + your caster level. This check does not use an action. On a success, the creature identifies the spell as Counterspell Snare and understands the backlash. On a failure, the creature only identifies it as a serious 8th-level or stronger magical threat.

Any creature that attempts to counterspell this spell is caught by the snare, whether or not their counterspell succeeds. A caught creature takes 15d8 entropic damage, is stunned for 1 round, and cannot attempt additional counterspells until the start of its next turn. If multiple creatures attempt to counterspell this spell, each one is caught separately.
