Speak With Small Beasts.

Awakened Mind.
Tauri's alien knowledge gives him the ability to touch the minds of other creatures. He can telepathically speak to any creature he can see within 30 feet of him. Tauri doesn't need to share a language with the creature for it to understand his telepathic utterances, but the creature must be able to understand at least one language.
Entropic Ward.
Tauri knows how to magically ward himrself against attack and to turn an enemy's failed strike into good luck for himrself. When a creature makes an attack roll against him, he can use his reaction to impose disadvantage on that roll. If the attack misses him, his next attack roll against the creature has advantage if he make it before the end of his next turn.
Once he use this feature, he can't use it again until he finishes a short or long rest.
Thought Shield.
Tauri's thoughts can't be read by telepathy or other means unless he allows it. He also has resistance to psychic damage, and whenever a creature deals psychic damage to him, that creature takes the same amount of damage that he does.
