"That's easy… Just hold this stone while performing the ritual. You should've learned of this in your class with Professor Shirley… It's called Oardic Prayer Stone and as you can guess, it can only activate if you're using Oardic in your chant. You don't have to use your voice and simply speak in your mind to complete the ritual… I've also prepared a few things in the other box to help you with your ritual." Professor Stella explained as she showed a gray stone that seemed to be an unpolished silver in front of the class.
She prepared 30 of them so everyone could try and summon one all at the same time.
On the other hand, Vale was actually feeling worried.
If one of his classmates summoned a dangerous spirit because of inexperience, mistake, or deliberate action, they might find themselves in a precarious situation.
He felt that Professor Stella was taking this test too lightly.
Luckily, Vale's concern was resolved by the student assistants.
