How do I beat Stygian?

the first time you see the giant worm you have to just get past him and continue on. near the end of the level you'll be reunited with Ruin (your horse) and you can then use ruin to run around and defeat the worm.

Ok you can still beat him without upgrading it

How do you kill the little worms??

This battle is a little easier if u upgraded Mercy but you don't need to have it to win. Mainly shoot shoot and shoot If u can try to get a few slashes in there this is dangerous though because you will be in his range if you are close enough to slash so mainly just shoot and keep riding and dashing and eventually you will kill him.

You can kill the smaller worms by shooting them it takes a while if you don't have mercy upgraded

Having issues with running around in circles shooting non stop, but that appears to be the only way to defeat the beast., pry the boringest boss of the game, but amazing game non the less.

If you're having trouble it may be the same glitch I encountered. No matter how much I shot at him he didn't take any damage. If this appears to be the case just die and start over to cancel the glitch

Use Ruin (your newley accuired mount) to ride alongside Stygian and hit the metal muzzle until it flies off, after that, whip out Mercy, hold down L2 and R2/LT and RT, keep moving, and dodge his little minions attacks. Good Luck.

Can you kill him from the platform of which you entered from? I can't seem to shoot and ride at the same time?? Been trying for two hours!!

Hold down lock-on, hold down r2 with mercy equipped, and speed boost (r1 i believe) when he gets close and does his "charge in to eat you" attack, it takes about 15 minutes or so, but thats how ya beat him.
