Zombie Triggers

Sight

Obviously, if a zombie visually sees you, it will automatically start trying to pathfind toward you. So, the best thing to do is not get seen.

Noise

Incredibly enough, zombies in this modpack are triggered by sounds! Whether that be you breaking a block, TnT going off in the distance, or you swinging your sword. Zombies are also very much attracted to gunshots. This is why suppressors are an absolute necessity if you want to remain stealthy. A zombie will move towards the sound source.

More information will be posted here soon, currently this is undocumented. Feel free to contribute to this.
