Insidious Suggestion (3.5e Spell)

Bannon listened to the sorceress 'Silly fighter you really shouldn't take on that ogre by yourself, you could die.' but he didn't care, he really wanted that ogre dead, even if he had to fight it by himself.

This spell work much like suggestion but much more subtle and tricky. First of all it allow the creature to take obviously harmful action at a +6 bonus to it will save, however it will still not take suicidal actions. If the affected creature fail it will saving throw, not only will it complete the suggestion but also reason that it was it idea all along. Even on a successful will save the creature is allowed another will save, unless it succeed the second will save it will not realize you attempted to use a suggestion on it.

Additionally insidious suggestion has a secondary boon, a reverse suggestion of some sort. You can deliver your suggestion into a sentence that specifically advise or suggest against what you want the creature to do, if the creature fail it will save it will perform the action you 'advised' against. By example you could word; "Don't go around punching random strangers in the face now.", if the target fail it will save it will start punching random strangers in the face and rationalize it was it idea all along.

Using either ability of this spell still require you to make your course of action you want your target to take sound reasonable.
