Ys Oath in Felghana Nightmare mode playthrough part 19 : Zellfel Zam Schutilger, the Savage Mongrel

Well I expected this battle to be a walk in the park, but apparently not. The first half of the battle generally go smoothly. I try to stick close to the wall on the left because it's easier to smash him with charge earth magic that way. As you can see, it's by far the easiest way to pile up damage against him, and you block attack at the same time.

So yeah, first half he'll be doing the same three things over and over. First, he'll spit fire. You can easily jump over him and score a few hit from behind when he does that. Be careful, sometimes he can use this 3 or 4 times in a row, and it can get dangerous. Also, the hitbox for it is a bit flawed, is you stand directly in front of him, you won't take damage. But this is a bad idea, because his second attack is a simple bite. The problem is that it's unpredictable and he unleashes it very quickly, and again, he can spam the hell out of it. If you're cornered, he'll rip your face apart. His third attack is simply the dash, you can simply jump over it. It's also the best moment to counter with the charged earth magic.

When he has less than half his health left, shit hits the fan. He gains two new attacks, one that is really useless ; he'll howl and a bunch of baby wolves will rampage through the arena. Just hover over them, and after you'll be able to score a lot of hits against that jerk.

Now the other attack seems to be largely impossible to fucking dodge, correct me if I'm wrong. He'll turn into a ball of fire and bounce all over the fucking place. There's not one single goddamn safe spot, not even in a corner. He can do it for a prolonged period of time, so earth magic won't allow you to block everything either. The best thing to do is to use your boost mode as a defensive tool, use your earth magic appropriately, and pray to your fucking gods, whatever they are.
