Blue Protocol: Star ResonanceFrost Mage GuideBest build and how to play the class.

Icicle Spec is entirely focused around gaining 20 stacks of its signature resource, Endless Cold. These stacks are used alongside its potent cooldowns to deliver a devastating two-phase burst rotation. The rotation kicks off with a flurry of Frost Lances, followed by an unrelenting Meteor Storm spam. When played right, it makes for an incredibly satisfying playstyle. But when making mistakes, expect to lose a large amount of damage. Due to its spammy nature during its burst window, Icicle requires good input speed to perform well. Without it semi-auto can be used, but at the cost of control over your character.

One quirk of Icicle is that it needs all its skill slots to deal max damage, leaving no room for Maelstrom without a skill swap. To get around this, it alternates between using its optimal DPS setup against bosses and reducing damage to utilize Maelstrom against packs of enemies.

The Frostbeam spec is entirely focused on executing lengthy channels of its namesake (Frostbeam) to take advantage of its ability to deal ever-increasing damage the longer you cast. While channeling, you’ll also multi-cast Frost Mage's other channeled ability, Tidepool, simultaneously for huge AoE damage. Frostbeam is the lowest action count class in the game, making it easy to play and ideal for those without fast reaction times, but it’s not great on autoplay.

The Spec has some quirks, though. While cooldowns are unavailable and resources are limited, you’ll have to start and stop your Frost Beam casts to conserve energy, and while using Frost Beam, your movement is heavily slowed.
