Skill Bonuses (1st level): You are trained in Arcana and Religion. In addition, you gain a bonus language chosen from the following list: Benthic, Draconic, or Mi-Go. Adepts who study the lore of alien races often need to learn how to use items or interpret lore not meant for humans.

Potent Lore (1st level): You can spend a bonus action on your turn to increase the level of the next. arcane spell you cast this turn by 2. This affects all level-based variables of the spell you are casting, including resisting counterspell attempts or casting at a higher level of effect. By calling upon the arcane secrets of alien races, star-lore adepts can create unexpectedly powerful magical effects.
You can use Potent Lore once, and then you must rest before you can use it again.

Mystic Signs (6th level): Through mystic gestures and motions, you can identify yourself as an initiate in unearthly lore to creatures that are otherwise hostile to humans and their ilk. You begin any interaction with intelligent extraterrene or extraplanar creatures with an attitude one step better than would otherwise be the case (Hostile becomes Indifferent, Indifferent becomes Friendly, and so on).

The Stars Are Right (10th level): Once during each character level at 10th level and above, you can call upon powerful alien entities to perform services for you. This functions as planar ally, except that can use the spell even if you are not normally able to cast it, and you call an extraterrene creature instead of a planar creature. You can conjure an extraterrene creature whose CR is no higher than one-half your character level.
