Karsha retrieved five orbs. The last battles yielded more than he had expected. Even Ayarr and Dhaka obtained an Avatar, a Tier 6 Avatar. Unfortunately, they are Servant-grade Avatars, so they cannot evolve. However, that's still an achievement—they managed to obtain something.
Karsha, who had obtained a legendary-grade sword from one of the quests, is now equipped with three swords and a dagger for the upcoming battles. He also obtained about twelve orbs, excluding the ones the five shadow guards acquired during the rapid massacres. Karsha, being generous, selected five for himself and gave the rest to the guards. He knew that without their help, he wouldn't have completed the quests on time.
They not only helped him farm for experience points but also filled up his Killer Points and skill points to the brim. He now has more than enough points to upgrade all his skills by three tiers once he reaches Level 2 of the Grandmaster stage.
