This is a docter nowhere mod that adds the filbus entity.
Requires gecko lib to work.
Filbus is a entity that will stalk you down. And hunt you down after a while.
Also you get a chair and can eat it ;-;
SPOLIERS ALERT
Filbus's AI works like this:
Filbus sinks within a 15 block radius.
Each tick the craziness value goes up 1 and starts at 0
When craziness is past 10000 and you go deep in caves you get darkness for 60 (3 seconds) ticks.
When craziness is past 15000 Filbus can attack you now.
