虽然非常反直觉，但是地狱骑士的可怖戒律需要六级才能选，这可能直接打死了地狱骑士这个变体的强度。
（如果我理解有误还请让我知道，我也想兼三级地狱骑士）
戒律(Disciplines)：一名3级的地狱骑士获得他的第一条戒律，
从与其特定骑士团相关的戒律中选择一个。6级时，地狱骑士获得第二条戒律，
从任何列出的对“任何骑士团”有效的戒律中选择。9级时，地狱骑士获得第三条戒律，从下文中列出的任何戒律中选择，即使其并不来自他自己的骑士团，唯一的例外是信念戒律。若一条戒律需要一个豁免，抵抗该戒律效果的豁免DC为10+地狱骑士等级+地狱骑士魅力调整值。地狱骑士每日可以使用任何戒律的次数等同于其拥有的戒律数量，即3级时她每日可以使用一次戒律。6级时，他每日可以使用两项戒律各两次。9级时，他每日可以使用三项戒律各三次。
劇透 - :
Disciplines: At 3rd level, a Hellknight gains access to his first discipline, choosing one associated with his specific order. At 6th level, the Hellknight gains a second discipline, choosing from any listed as being available to “any order.” At 9th level, the Hellknight gains his third discipline, choosing this one from any of the disciplines listed below, even those from another order, with the exception of pentamic faith. When applicable, the save DC to resist a discipline’s effect is equal to 10 + the Hellknight’s level + his Charisma modifier. The Hellknight can use any one discipline a number of times per day equal to the total number of disciplines he has access to, so at 3rd level he can use his discipline once per day. At 6th level, he can use both disciplines twice per day each. At 9th level, he can use all three of his disciplines three times per day.
可怖(Fearsomeness，特异能力；
任何骑士团)：若地狱骑士使用威吓技能使一名10尺内的生物战栗，他可以改为使该生物变为惊惧。
