HOLIDAY WARRIOR [General]
Whether you're pro-Christmas ("there's a war on Christmas!"/"I am insulted that you wished me Happy Holidays!") or anti-Christmas ("your cultural appropriation of the trappings of dead pagan religions offends me"/"I feel violated by your Christmas decorations!"), you are a brilliant at ruining everyone's good mood and holiday cheer.
Benefit: Whenever the character is within 30 ft. of Christmas decorations, or other items related by Christmas, or someone brings up anything related to Christmas or wishes him or her "Happy Holidays!", you gain a +4 bonus to Intimidate skill checks, as well as a +2 bonus to all melee attack rolls. You also impose a -2 penalty on Morale checks. The effects last until the character leaves the area.
