Hello everyone and welcome to my 23rd analysis, this time featuring Frostbite.
Overview: Frostbite is one of the most unfortunate monsters in this game. His moveset is godly for a denier, featuring multiple Stamina Drains and Freezes, alongside a move that gives all allies Double Damage and 50% Stamina. These are good and all, but Frostbite has almost unusable Speed for a denier and his trait is trash, making him extremely vulnerable to anything faster than him - which is almost any denier you'll se in the current metagame.

-Glacial Snowstorm
-Piercing Rainfall
-Arctic Boost

Runes: 3 Speed/3 Team Speed
Mutant Rune options: Speed&Life, Team Speed&Team Life

Build Explanation:
Glacial Snowstorm can deny an enemy for 2 turns and the others for 1, and it can also be used to deal with Dodge Area; target the Dodge Area monster with it and it'll at least get its Stamina Drained. Piercing Rainfall is another AOE deny move. Arctic Boost is a very powerful supportive move that counters Stamina Draining effects like Wangzhou's SC or Stamina Leak, and it also gives your team Double Damage. Lastly, Icy Leech is a single target 100% Stamina Drain that also gives Frostbite 40% Stamina, useful against Freeze Immune monsters.
3 Speed with Life Mutations is standard on deniers, but since Frostbite is low on Speed, you might want to make him a secondary denier with 3 Team Speed instead.

Teammate Options: A Skill Mirror monster will allow Arctic Boost to fully restore your team's Stamina. For more Teammate options, check out this article.
