The newest S+ clan added in the Ice Update (April 8, 2026). Frostbane is currently rated the strongest clan in the game — essential for unlocking the Ice Queen sword's V Move. Provides the highest combined damage and HP of all clans, plus a sword-specific bonus that makes it ideal for sword builds. Requires the Ice Queen sword synergy for maximum potential.

Frostbane's damage stacking passive rewards sustained DPS output. Each damage tick (not just hits, but damage over time effects as well) adds a 0.00225x multiplier to your next hit, stacking up to a maximum of 1.25x damage. After reaching the cap or 6 seconds pass without dealing damage, the stacks reset. This makes Frostbane exceptionally strong for fast-attacking builds like sword builds, particularly when paired with the Ice Queen sword which it unlocks.
Builds that synergize well with clan bonuses:
When starting the game, you receive a random clan. Higher-tier clans are rarer. Use a Clan Reroll item to get a new random clan. S+ tier clans require significant reroll investment.
