Survival becomes less predictable when familiar creatures no longer behave exactly as expected. This addon revises vanilla mob AI and strengthens encounters, targeting players who want a harder journey through the ordinary game rather than a separate adventure map.

A different survival challenge
The changes are intended for players who already know ordinary survival, speedrunning and the path to the Ender Dragon. Familiar encounters can require a different response because creatures receive altered AI and individual behavior.
The current release includes a behavior revamp. According to the author, achievements remain available and experimental world features are not required.
