War Sight (Su)
Source: Advanced Player's Guide, p. 46
Whenever you roll for initiative, you can roll twice and take either result. At 7th level, you can always act in the surprise round, but if you fail to notice the ambush, you act last, regardless of your initiative result (you act in the normal order in following rounds). At 11th level, you can roll for initiative three times and take any one of the results.
