Awareness,Vigilance,and Courage
Are not so much 'House rules',but rather,existing mechanics given a name.Their purpose is to speed game play by eliminating unneeded opposed rolling.This reduces variance.
· Awareness- is nothing more than 'Taking 10' on Perception.
(See the new Stealth rules thread for further details*)
· Vigilance- is the DC the core rules require for purposes of feinting.It is 10+Base attack+Wisdom bonus.If you are skilled in sense motive you may instead use 10+Sense motive for your Vigilance score(be sure to notate it.) Improved feint gives you +2 Vigilance,Greater feint gives you +2 more.
· Courage- is the DC the core rules require you to roll for purposes of Intimidating someone.Any feat or ability which increases saving throws versus Fear also increases ones Courage score(ex:Fighter's Bravery)
