For the strength test, the prize for winning first place was the exclusive Mana Lord subordinating skill and 10 mana comprehension crystals.
The first time that Sebastian saw the term 'Mana Lord subordinating skill', though he didn't understand exactly what it meant yet, his intuition told him that it was special and it drew his attention immediately.
When Meuer, the Mana Lord who won 1st place in the speed test finally got to take his reward, Sebastian paid careful attention.
The transfer of information between the Red tier Mana Lord then seemed to be mental or through an illusion, but Meuer's intoxicated look at the end and his words enabled Sebastian to make a lot of educated guesses.
The Red tier Mana Lord's so-called Celestial Beast that appeared at the end that induced the phenomenon that brought the clusters of dew-like primordial mana to converge in the temple gave Sebastian a lot of other clues.
