What are the requirements to unlock the Hot Blooded achievement in Honkai Star Rail?

The Hot Blooded achievement unlocks after defeating Cocolia, Mother of Deception, without any ally being Frozen at any point of the battle in Echo of War. Since her abilities are guaranteed to freeze allies during combat, getting the achievement might seem impossible at first.

However, with a proper strategy, you can easily knock out the weekly boss in Honkai Star Rail without getting frozen. Additionally, you must unlock The Stone of the Everwinter Monument consumable before the battle, since it is the only item that increases the Effect RES to Frozen of all allies by 50%.

While some consumables are craftable by default, a few, on the other hand, are locked behind recipes, which you can purchase from various NPCs. Likewise, the Stone of the Everwinter Monument, which is an integral item to complete the achievement, is typically sold by Launder at Jarillo VI’s Boulder Town.

Launder works at one of the grocery stores in the area, located beside the Goethe Grand Hotel. Simply teleport to the hotel; he should be visible, given that he is the only marked vendor in the vicinity. Approach him and interact to open his shop. Here, you can purchase the recipe for The Stone of the Everwinter Monument in exchange for 120 Shields.

After acquiring the recipe, access the Omni- Synthesizer from the Parlor Car or the in-game menu. Select the item from the list and choose the quantity, which in this case should be one, since its effect applies to the entire team. Finally, hit Synthesize to obtain the consumable.

This will, however, cost you 3x Core Ice, 3x Preservation of Construction Material, 2x Hard Chip of Nihility, and 1x Tier Crystal of Glorious Death. Hence, pre-farming the resources is advised to save some time. Once you have everything ready, head over to "Cavern of Corrosion: End of the Eternal Freeze" to defeat Cocolia and collect the Hot Blooded achievement in Honkai Star Rail.
