HFW | Apex Thunderjaw (Coward mode) | Hunter Bow only | Ultra hard, NG+ 

There is an area where you can hunt an Apex Thunderjaw without putting yourself in serious danger. It's surely not the bravest way to kill this great machine, but it works, and requires almost no skill.
This is done with quite good gear, but it works also with weaker weapons. The most dangerous parts are the Disc Launchers - remove them first.
