You approach Saint-14; the crest of his helm brims with sunlight. "You are ready for a mighty tournament!" He straightens his stance and looks you over.
"You will not win the Trials of Osiris with only strength. Here, we test teamwork!" His voice rises, punctuating the final word. "You should fight with those you trust. If you fall, your friends must bring you back in the fight."
Saint leans in, and he sounds more like his usual self. "Do not worry! Even defeat teaches lessons. If you lose, you can test yourself against other defeated Guardians. Or start over and try again, until you are undefeated." You can almost hear the grin in his voice. "Fight hard, and you will be rewarded. But better rewards if you win, yes?"
