The next stage of the Penacony questline is now live in Honkai Star Rail with the release of version 2.2, and there’s a tough boss battle with Argenti waiting for players partway through the latest Trailblaze Mission.
After repairing the Big Ticker in the Seabiscuit quest during the version 2.2 Penacony storyline, you have to defeat Argenti in the Superstar Showdown. Defeating him will net you the “The Ultimate is Eternal Sincerity” achievement, but you can actually earn a secret achievement called “Sincerity is Eternally the Ultimate” by choosing specific dialogue options and avoiding the fight entirely.
How to Get the Sincerity is Eternally the Ultimate Achievement in Honkai Star Rail
When you encounter Argenti during the Seabiscuit quest in Penacony, there’s a brief dialogue segment before the boss battle begins. If you reveal the truth about the Stellaron and the Watchmaker to Argenti, he’ll let you pass without a fight. Choose these dialogue options to bypass the boss battle.
- “I’m busy saving the world. Could you please make way?”
- “We need to seal the Stellaron on Penacony.”
- “Tell the truth about the Watchmaker and the Stellaron.”
After choosing these three dialogue options, Argenti will let you pass and you’ll earn the Sincerity is Eternally the Ultimate achievement. This will net you 10 Stellar Jades that you can use to pull for new characters like Robin. Fighting Argenti locks you out of getting this achievement, but the other achievement (The Ultimate is Eternal Sincerity) gets you the same rewards. It’s the situation as previous choice-related achievements in Honkai Star Rail.
By the time you reach Argenti in the Seabiscuit mission, you’re nearly done with the version 2.2 Penacony storyline. There’s still a lot of Honkai Star Rail content left after this point, though, so make sure you’ve collected all the chests and items in new areas like Dreamflux Reef so you can get as many Stellar Jades as possible.
