(General)
Your enchantments inf luence targets in more subtle ways and are harder to notice.
Prerequisites
Deceitful,
Spell Focus (enchantment).
Benefit
When you cast an enchantment spell or use an enchantment spell-like ability to inf luence a creature's attitude or actions and the foe negates the spell with a successful
Will Save, she has a 50% chance not to notice that she just succeeded at a saving throw (she still can attempt to identify your spell or spell-like ability as normal). If the foe fails the saving throw or is otherwise affected by the spell, the
Sense Motive DC to notice she is under the effects of an enchantment increases by 5.
Normal
Anyone who successfully saves against a spell notices the mental intrusion automatically.
