The High Morality Praise is a special item in Honkai: Star Rail that could previously be obtained in exchange for certain lines and actions, and then exchanged to perform morally questionable actions. This changed in version 2.5, when the High Morality Praise merchant was added to the game, interacting with which allows you to unlock the secret achievement “Sublime Deal Object”.
How to Unlock the “Sublime Deal Object” trophy
In the mooring area of the Skybreaker ship, you can find a merchant named Northern Beggar. From the anchor, simply climb the steps where the NPC we need is sitting. Go up to him and start a conversation.
The Beggar will ask us if we have seen anyone with a ram's horn on board the ship. From his subsequent description, we can understand that the merchant is looking for the Duke of Infernal Fire. They were supposed to meet, but now it is impossible thanks to Acheron. After that, the Beggar will suddenly hint to us that we should offer him something.
You can choose any of the three lines that appear, this will not affect access to his shop, where you can purchase a one-time “Large High Morale Set”, which will give you as many as 10 units of this item, and 3 units of High Morale Praise. Its stock is updated every seven days.
To get the achievement, you will need to buy any item from the Northern Beggar. After that, we will get the bronze achievement “Exalted Deal Object”, which gives five pieces of star jade.
