0:50 Frostarm Lawachurl Fight
So Frostarm Lawachurls are the Cryo versions of the Stonehide Lawachurls that you can find in the Dragonspine area. These guys have slightly different attack patterns from their Geo counterparts but I would argue that they're actually easier. Just focus on taking down their shield first, and you won't have any issues.
If you want the Achievement, you need to kill the Frostarm Lawachurl without taking down its shield, so use a unit that isn't effective against Cryo Shields.
MANDATORY UNITS:
Technically none, but bring a Pyro Unit if you don't feel like getting the achievement or if you just want to get the job done fast.
RECOMMENDED UNITS:
Just about any Pyro Unit with decent DPS.
Amber (F2P + Good Pyro DPS + Aggro Control)
Xiangling (F2P + Good Pyro DPS)
Diluc (High RNG + Good Pyro DPS)
Klee (LIMITED Unit + Nothing but Pyro DPS)
Bennett (Medium RNG + God Tier Physical to Pyro Conversion)
Superconductors:
Lowers defense pretty well for some extra DPS.
Lisa (F2P + Nothing but Electro DPS)
KeQing (High RNG + Strong Electro DPS)
Razor (Medium RNG + Hyper Tier Electro DPS)
Fischl (Medium RNG + Good Electro DPS)
I beat my first Frostarm Lawachurl on accident because it got caught in the crossfire.
