With the release of Honkai Star Rail's update 2.5, you have access to Rappa and an event called Luminary Wardance Ceremony. This is one of those events with a bunch of stages, but they're released all at once instead of once a day.
Luminary Wardance Dreamscape Training All 5 Challenges S-RANK Trial Characters Honkai Star Rail
This new event pits players against a daily challenge with a total of five stages. After completing the story battle between Luka and Gepard, the conversations, and the tutorial battle, you’ll gain access to the meat of this Xianzhou Alliance battle tournament, where you can get the best rewards.
Everything you and your enemies do earns you Vibes. The goal of the game is to fill your Vibe meter before the enemy team can fill theirs, as a full Vibe meter will fill all of your Ults and buff your team. In the tutorial, you'll be focused on the break effect to earn the most Vibes; you can't change your team for this, but combat is pretty easy even when the enemy's Vibe meter is full.
You should also be aware of something called a Tactical Codex. For the tutorial, when the Codex is in effect and you use your Ultimate, you gain Weakness Break Efficiency and are also 100% action advanced.
