The battle priests of Varkun started to pray to the God of War Varkun for the blessing of unbending courage.
This was one of the support spells they could use on others. It guards the heart from fear, the mind from outside manipulation, and the eye to see through illusions. Since they were still beginner battle priests, they didn't have much more capability than this.
The Mystic Clerics of Naerith prayed their hardest for the blessing of the forest. It allows those under the blessing to gain a slight increase in their overall abilities while in a forest.
The mages also did their best and used whatever support spells they knew of and poured them onto the four.
Once he felt the power of the support spells and blessings, Thrall dropped low, palms pressing into the snow.
