This was a comment about Tremblor having 10k effective HP and being a perfect example of what I was talking about originally, plus the guides saying to go grind Unborn Valkyrs, which I’ve never had any luck at.
Then I noticed a detail that I think was omitted from the world quest text, and obfuscated by the fact that when you click a boss battle it starts the battle, so you can’t click it then hover over the buff on it and see that it can be depowered if you beat the Slyvern pets nearby.
I was getting a Legendary Tremblor down to <1k with 3 pets before noticing that, so I beat it with just 2 pets after knocking it down to a Rare. I like that the battle had a meta element that added extra fights to make the final fight more doable, and the fact that beating the boss awarded it as a pet.
I just wish it had been more clearly communicated. I didn’t see any indication initially that I should go beat the Slyverns. In fact, I don’t think they had loaded onto my screen by the time I started the first fight, and from then on I had my back to them because Tremblor is on a ledge. I don’t think the buff telling me to beat the Slyverns was visible during the fight, either.
This is the first time I’ve ever seen such a twist on pet battles so it threw me.
