"Please use it, I have more!" Kence replied to his guard honestly. Otto is still the King's brother and part of the Royal Family, he can afford to buy quite a lot of Rank 3 Runes
Kence even felt that it was a pity as the only Rank 3 Runes that he has are defensive ones. Even if he has an offensive one, it still required the mage to control the power inside the rune
Magic Warrior's soul cannot take the burden of wielding such power and those runes cannot be used by Kence
The guard still has an unsure look on his face though. Kence might be 'rich' but the guard isn't. He can't afford something as expensive as the rune on his hand
Seeing this, Kence tried convincing his guard again. "If you die, I will die too! Please use the rune!" Kence shouted and the guard cannot answer as the snow golem already reached him
