The [Temple of Vasiliás] dungeon was made to be one of the toughest for current players. In fact, it was so difficult that according to the AI overseeing the game, no team would be able to complete it for the next 2-3 days(RT). This included Seven Star Glory, aka Team Sato.
Gatekeeper Baka was the first BOSS in the dungeon and it was a level 15 Special Elite monster that couldn't be easily rivalled. Though it was way weaker than King-ranked Kobold King, it was powerful in its own way. According to the system, only Seven Star Glory would be able to defeat it as of now, but if they were to underestimate it and not figure out the trick behind the monster, they would suffer a team wipe.
-67 (1322/4500 Gatekeeper Baka's HP)
After Sato's last attack, the Gatekeeper's HP had gone below 30% and it entered its berserk mode.
