Honkai: Star Rail How To Get 2 Hoolay Achievements

During the Trailblaze Mission [Finest Duel Under the Pristine Blue: Part 2], you will face Hoolay. You can get 2 achievements by battling Hoolay. If you missed these achievements, then you need to wait until Hoolay enters Memory of Chaos or another end-game. Here are the 2 achievements you can get from this boss and how to get it.

How To Get 2 Hoolay Achievements

1) Lone Wolf's Howl

There are no other Wolftrooper enemies on the field when Hoolay triggers Moon Rage. You can battle Hoolay twice during the Trailblaze Mission [Finest Duel Under the Pristine Blue: Part 2].
First of all! Look at the image above for the two items I've circled.
Bloodlust is the stacks that Hoolay got when he and any Wolftrooper attack your characters. When he obtains 6 stacks of Bloodlust, he will enter Moon Rage state.
Summons the Packs in the Action Order will summon one Wolftrooper when it takes action.

What you need to do is to make sure Hoolay gets his 6 stacks of Bloodlust (he can get this easily) to enter the Moon Rage state but you also need to make sure that there is NO WOLFTROOPER beside him.

This strategy depends on your team, but generally, what I did here is:
(1) Right off the bat, the enemies will attack you 3 times; 1 from Wolftrooper and 2 from Hoolay. This way, he'll get 3 stacks of Bloodlust. After that, keep attacking like normal but save your Ultimate for now.

(2) After the Wolftrooper hits you for the second time and Hoolay's stack increases to 4, immediately use every Ultimate you have to DEFEAT THE WOLFTROOPER. That way, after Hoolay's turn comes and he attacks you 2 times, his Bloodlust stacks will increase to 6 and he will immediately enter the Moon Rage state. But there will be no Wolftrooper beside him and you will get this achievement.

2) Veiled Moon, Ceased Sheen

Hoolay could not unleash "Lupine Chase Calls Bloody Gleam" in Moon Rage's duration. This can be a continuation of the previous achievement. Once Hoolay enters Moon Rage state, his Bloodlust stack will change to Irate stacks. He will gain an Irate stack every time he hits your characters. But you can COUNTER AND REDUCE THE STACKS by attacking Hoolay back.

Once the Irate stacks reach 6, he will unleash Lupine Chase Calls Bloody Gleam, the one thing you want to avoid to get this achievement. So what you need to do is attack him relentlessly so he won't get 6 stacks of Irate. Once his Irate stacks reach 0, his Toughness will be reduced, and reset Irate to a set number of stacks. Do this multiple times until he Weakness Breaks and gets out from the Moon Rage state.
