This mod significantly enhances mob artificial intelligence, forcing them to attack only those creatures they can directly see.

Sound Detection System (starting from version 1.19.2-4.0.0)

Regular mobs completely ignore the sounds of your footsteps, but if you make some strange or suspicious noise - be careful! Monsters will immediately hear it and go searching for the sound source. The same thing happens when an arrow gets stuck near them.

Don't worry about conflicts with the Warden - both sound detection systems coexist perfectly with each other.

How does the visual detection system work?

Mobs will no longer damage you if you're standing behind their back - they need to directly see their target in their field of view. This eliminates the old flaw where enemies could attack through walls or without direct line of sight.
