with a white tiger added. Ruins are very rare in the snowy mountains, it's recommended to directly use /locate structure whitetiger_boss:tiger_lair To summon the White Tiger, you need to

use the Beast Summon Bell and hold right-click for three seconds
Before being awakened, it is in a sleep state and can't be attacked.

Leaving or failing will reset it.
The current attack methods are Hupu claw swipe, biting, fast melee claw swings, stomping, and tail whipping, as well as releasing icicles and surrounding cold damage.
This is my first test version, enjoy.
