Karsha is ready, I think...

"Big brother, make sure you kill the bad guys so that Starr can fly around with you," the little snake girl said as she hugged Karsha one last time before he left for his final quest: killing the ten overlords.

After transferring skills to the five shadow guards, Karsha also used the runes he had learned so far. He applied [Silent Breath], making them nearly invisible. Ayarr, with her natural assassin skills, benefited greatly; unless a Tier 6 monster is a Terror or Calamity Mutant, sensing her would be impossible.

He also applied [Self-Heal] runes to their bodies, granting accelerated healing and a 200% boost to their defenses. Since this buff only lasts for five minutes, Karsha stacked the runes multiple times, ensuring they would last longer when activated.

But that was all he could do for them. Knowing his mastery wasn't great, he avoided complex runes that required more soul power and mental strength to draw.
