|A massive axe that looks like it was carved from a glacier, or possibly calved from one. It leaves ice crystals in its wake as it swings through the air, and grants its wielder immunity to freezing vapours.|
Using Frostbite can be somewhat risky, as the noises it makes while fighting will attract attention from beyond your LOS. On the other hand, it's a highly enchanted freezing-branded executioner's axe, one of the weapons best suited for cutting through hordes of foes. It also provides one level of cold resistance, the ability to fly, and occasionally drops freezing clouds on your targets without any spell hunger costs, which can increase your damage output on particularly durable enemies. The clouds may also come in handy in covering your escape should the noise attract too much attention. The added immunity to freezing clouds is a further bonus, allowing you to walk through the clouds cast by your weapon as well as from any other source (such as the spell).
Prior to 0.19, Frostbite did not grant immunity to its freezing clouds.
Frostbite was added in 0.18.
