Completed the DLC took me about 2 hours to do so still missing 2 trophies.
Lord Of The Hunt "menu" separate from story mode a new test mode(have to kill 5 warchieves 20 captains and the new beast)
There are about 10 story missions (of these are warchief ones)10 journal collectibles,about 5 challenges which reward you with a caragoth mount special it sets your beast on fire and anyone nearby it gets ignited.
You also get 5 new epic runes but you cant use the ones from the story mode except for the DLC ones like power of shadow.
These are mount based like draining the beast wont use their health.
Wretched Graug has no meele attacks it has an areal poison vomit and a projectile which is used instead of the bow.It also regenerates health really fast after consuming an enemy.Now there are also graug bait scattered around which are hanging from ceilings kinda like the other bait but they are smaller.
The caragath has stealth attack both from behid and above and the movement is silent as well if you hold r2.
It has elf swiftness as well when using it time slows for a few seconds.
You can also find many ghoul bait on the grounds after a certain point you can brand them by using wraith burn.Its pretty difficult since you have to build up the meter to 5 for the special and most of them are 1 hit kills.You can also use them to take down graugs after stunning them with a double headshot.
The new bosses are pretty fun to play but they arent that much different except for the mounts.
Heads up to anyone who has this. They added the nemesis forge for you to import your top nemesis and follower to the new game. You do still need to own the game to do this though. If you have separate save files, you'll be able to take over both.
