A trap?

[Ding. Spell failed to activate]

Liam stared at the notification once his vision cleared and the pain subsided. 

It looked like he was not able to summon these undeads and even suffered some sort of backlash from trying to do so.

"Hmmm. Was it because their levels were comparable to mine?" He pondered for a few seconds and that seemed to be the most plausible answer.

"There are too many things I don't know about this class. Too bad these would have been useful in the fights."

Liam clicked his tongue and unwillingly left the three snake corpses behind. He looked around and decided to head towards his right, where a group of demons had gone.

Before long, he heard loud battle noises, and a few feet ahead of him a group of five demons was fighting against four nagas.

There seemed to have been casualties on both ends with two nagas and three demon beast hybrids already down.
