When you choose this archetype at 3rd level, you gain proficiency in two of the following skills of your choice: Arcana, History, Insight, Investigation, Nature, or Perception. You can gain proficiency with a tool of your choice in place of one skill choice.
When you choose this archetype at 3rd level, you gain a set of abilities that are fueled by special dice called superiority dice.
Superiority Dice. You have four superiority dice, which are d8s. A superiority die is expended when you use it. You regain all of your expended superiority dice when you finish a short or long rest.
You gain another superiority die at 7th level and one more at 15th level.
Using Superiority Dice. You can expend superiority dice to gain a number of different benefits:
At 3rd level, your study of the supernatural gives you a limited ability to use magic. You can cast Detect Magic as a ritual. You can cast Protection from Evil and Good , but you cannot cast it again with this feature until you finish a long rest. Wisdom is your spellcasting ability for these spells.
In addition, you gain the ability to speak one of the following languages of your choice: Abyssal, Celestial, or Infernal.
At 7th level, whenever you expend superiority dice to add to a damage roll, you can expend up to two dice instead of just one, adding both to the roll. Both dice are expended as normal. If the target of your attack is an aberration, a fey, a fiend, or an undead, you deal maximum damage with both dice, instead of rolling them.
At 10th level, your superiority dice turn into d10s. At 18th level, they turn into d12s.
Starting at 15th level, when you roll initiative and have no superiority dice remaining, you regain one superiority die.
