Inside The Great Tomb of Nazarick the guild members and NPCs are stronger than those who are not from there. Basically inhabitants of Nazarick gets a powerup or a permanent boost as long as they're inside, which makes it harder for other players to beat them or impossible to beat 1v1.

I don't know how big this boost is, but lets say 5 levels higher than yourself alone might take 2-5 players to defeat (just a guess, but I know it takes at least 5-15 to defeat someone 10 levels higher than yourself). It was written in the LN that it was impossible to defeat someone 10 levels higher than yourself and I think Lakyus stated adventurer teams could defeat enemies 5 levels higher than themselves, but not higher (by YGGDRASIL standards. 15 by NW standards).
