Frostcrush Valari

The Frostcrush Valari is a craftable Hardmode rogue boomerang that is a direct upgrade to the Kylie. It automatically throws a slow-moving boomerang that travels a long distance before returning to the player. When contacting an enemy, several gravity-affected ice shards will be released from the boomerang that deal 33% of the boomerang's base damage. Each boomerang inflicts the Frostburn and Crush Depth debuffs onto enemies. There is also a 20% chance for the Glacial State debuff to be inflicted.

Performing a stealth strike with the Frostcrush Valari will cause three boomerangs with much lower range to be thrown, alongside a spread of slow-moving icicles that are very lightly affected by gravity and shatter after about 3 seconds.
