Inspired Stratagem 
Feat 8
Source Pathfinder Advanced Player's Guide
Trigger One of the required allies is about to attempt an attack roll or skill check.
Requirements You spent 10 minutes during your daily preparations reviewing stratagems for the day's adventures with up to four allies.
You quickly advise your ally, using your earlier planning to make sure luck can't throw a wrench in the cogs of your schemes.
The ally rolls the triggering check twice and takes the better of the two results. That ally then becomes temporarily immune to your Inspired Stratagem until your next daily preparations.
Effect: Inspired Stratagem
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
FortuneA fortune effect beneficially alters how you roll your dice. You can never have more than one fortune effect alter a single roll. If multiple fortune effects would apply, you have to pick which to use. If a fortune effect and a misfortune effect would apply to the same roll, the two cancel each other out, and you roll normally.
LinguisticAn effect with this trait depends on language comprehension. A linguistic effect that targets a creature works only if the target understands the language you are using.
RogueThis indicates abilities from the rogue class.
