Cerberus, a gigantic three-headed dog, is said to have guarded the doors to the underworld since the beginning of time. Since it had three heads, its intelligence couldn't be underestimated. Furthermore, as its body was constantly burning, as if coated with molten lava, attacking it directly would cause the attacker to receive some damage in return.
In other words, the dragonkin girls are forced to challenge the Cerberus in a magic battle. However, for that to succeed, there's one thing that's getting in their way.
"That necklace hanging on the middle head—it's something that blocks spells," Indra relayed as they charged forward. "From testing it earlier, we found that it has a short cooldown of 0.1 seconds, and its duration lasts for exactly five seconds for each activation."
Sandra squinted her eyes, catching a shadow of what looked like a necklace, as Indra said. However, it seemed to be embedded in the Cerberus' body, making it difficult to destroy.
