Impenetrable Illusion

(Metamagic)

Your illusions are harder to see through. This has the following effects:

• When someone sees through your illusions, allies get a +2 bonus to their saves instead of +4.
• Invisibility Purge has a 20% chance of failing against you.
• True Seeing has a 10% chance of failing against you.

This feat increases the spell level by 1. It may be applied to a spell more than once, and the bonuses stack (to a maximum of +0 to saves, 100% failure for Invisibility Purge and 50% failure for True Seeing).
