I hope Dag goes back to his clan and learns more runes along with learning runes from other clans. I dont know how many runes cloak boy used in this fight but it did not seem like he used all that much. Maybe he has some related to other fields or healing techniques. Dag needs to increase his utility he needs technique to defend others and to heal in the case of an emergency,if Karl is not around. Also having a few more AOE attacks would be nice.
Magni in his fight with the Renegade king used like 5-6 runes at most but he had a bunch more or at least that is how it was described.
