Well, Aura is useful for Evaluation, taming and influencing people. (Breath pheromone skill.)

Shalltear is there for security, additional Teleport and miscalleneous.

Both are really there because Ainz wanted to combine an exploration/Diplomatic mission with team building exercise between Aura and Shalltear (Aka.: Even an Lich Overlord needs comedy from time to time.) and, most importantly, because those two have had nothing better to do.
