You should bewell-prepared before entering these areas, as they are often crowded with high-level enemies. It’s recommended to use at least Tier 3 weapons to deal with them more easily.

While Chalk Peak is generally recommended for players level 32 and above, lower-level players can still explore the area if they stay clear of the Elite enemies. However, if you’re around level 25, you can easily take down the enemies in these strongholds.
