Ep. 4: Goblin Slayer's group battles an Ogre general using stealth and a secret water magic scroll.

Goblin Slayer's group enters the ruins where he notices there are no totems, suggesting these goblins are not led by a shaman. After rescuing an elven prisoner tortured by goblins, an angry High Elf Archer vows to avenge her fellow kin. The group finds a hall where the goblins are resting. Using sleeping and silence spells, Goblin Slayer's group kills the sleeping goblins without alerting the others. However, their silence alerts the goblins leader, an Ogre, one of the Demon Lord's generals. The Ogre attacks the group using his strength and fire magic and proves difficult to kill due to his large size and ability to heal quickly. With his allies at their limit, Goblin Slayer uses his trump card, a magic teleportation scroll given to him by Witch, which sends strong jets of water from the bottom of the ocean to seriously damage the Ogre before giving him the killing blow. As Elvish reinforcements arrive to take over the ruins and Goblin Slayer's group heads back to the city, the experience she had with Goblin Slayer and his obsession makes High Elf Archer want to take Goblin Slayer to a proper adventure.
