Exploring the Otherside means sharing the deep underground with dangerous sculk creatures, which would normally wipe out wild spawns before you could reach them. This data pack stops those hostile mobs from hunting the Pokemon around you.
How Sculk Mob Protection Works
When wild Pokemon spawn inside the Otherside, the data pack prevents the dimension's sculk mobs from targeting and attacking them. It relies on specific mob tags included in newer updates of the Deeper and Darker mod to mark wild Pokemon as safe from harm. Because of this, wild creatures can wander the dark biomes undisturbed instead of taking constant damage or dying off-screen while you explore.
What to Check If Sculk Mobs Attack Pokemon
1. Observe how nearby sculk mobs behave when a wild Pokemon wanders close to them.
2. If sculk mobs still aggro onto wild Pokemon, verify that your game is running a newer update of the Deeper and Darker mod that supports those mob tags, and confirm the data pack is active in your world's datapacks folder.
3. Keep in mind that this protection only shields wild Pokemon. Sculk mobs will still target you normally, so clear out nearby threats or sneak carefully before starting a battle in crowded areas.
