Mini Ice Star

Star Shatter

A demonstration of the Kelvin Catalyst being thrown. Note how the ice shards summoned by hitting each enemy only home in on the Super Dummy when the blocks become actuated.

The Kelvin Catalyst is a craftable Hardmode rogue boomerang. It inflicts the Frostbite debuff and multiple boomerangs can be deployed at once, with the boomerang returning to the owner after a set distance and breaking upon contact with a solid block. Upon contact with an enemy, the boomerangs spawn five ice stars each, which do 50% of the boomerang's base damage, sharply home-in onto enemies, and go through tiles. If no enemies are nearby, the ice stars will shatter. There can only be up to 32 ice stars at a time.

Performing a stealth strike with the Kelvin Catalyst will cause the next boomerang thrown to ram towards the nearest enemy instead of returning to the player and will return to the player 1 second later.

Its best modifier is Flawless.

Notes

• The ice stars deal typeless damage and cannot deal critical hits.
• Most of this weapon's materials can be obtained from Cryogen. The only exceptions are the Ice Stars, which are bought from the Archmage NPC who spawns after Cryogen is defeated.
• This weapon is extremely effective in early to mid-Hardmode, as it can tear through most bosses at that stage of the game with its high DPS.

Trivia

• A catalyst is a substance which increases the rate of chemical reaction but is not consumed upon reacting, thus it can react repeatedly.
• Kelvin is the SI unit of temperature.
