Some dark knights feel the call of black magic more closely than others, focusing on reaching greater heights.
The fell knight is an archetype of the dark knight class.
Fell knights gain the ability to cast black magic spells at 1st level, instead of at 4th level with dark knight spells, as seen below. In addition, a fell knight gains additional MP for having a high attribute (Intelligence).
This ability modifies and replaces the dark knight’s spellcasting ability.
Unholy Steed (Su)
Upon reaching 5th level, the fell knight gains the ability to gain the service of a yellow chocobo to serve her in her crusade against good. This mount functions as a chocobo knight’s animal companion, using the fell knight’s level as her effective chocobo knight level.
Once per day, as a full-round action, a fell knight may magically call her mount to her side. This ability is the equivalent of a spell of a level equal to one-third the fell knight’s level. The mount immediately appears adjacent to the fell knight. A fell knight can use this ability once per day at 5th level, and one additional time per day for every 4 levels thereafter, for a total of four times per day at 17th level.
At 10th level, a fell knight’s mount becomes a black chocobo.
At 15th level, a fell knight’s mount gains spell resistance equal to the dark knight’s level + 11.
Should the fell knight’s mount die, the fell knight may not summon another mount for 30 days or until she gains a dark knight level, whichever comes first. During this 30-day period, the fell knight takes a –1 penalty on attack and weapon damage rolls.
This ability replaces the dark sword tech abilities.
