SP Hakuya — Ice Crystal Burst
Silver Knight amplifies ice critical hits and extends freeze duration, directly feeding Hakuya's entire kit — more crits, longer freezes, more Overload ticks.

Emerald/Emerald/Diamond| Star | Branch | Effect |
|---|---|---|
| T0 | Ice Mastery | Ice Crystal Burst radius 2 → 4. +25% base crit rate |
| T1 | Ice Vortex | Crit hits freeze target for 1.5s. On death: trigger Ice Crystal Burst |
| T2 | Frost Crit | Gain crit rate, crit DMG, skill DMG = 25% of ice ATK (DOUBLE-DIP) |
| T3 | Overload | Frozen targets: 4 ticks/sec of 200% ice DMG (10x scaling), max 5 layers |
Perma-Freeze Ice Nuke. Tier 2 double-dipping converts ice ATK into crit stats — Lazulite gems give 4 stats in 1. Perma-freeze via Tier 1 + Overload ticks melt frozen targets.
Skill: Ice Crystal Burst
Deals 2000% ice DMG in a radius 2 circle around the target (20x ice scaling).
Massive base multiplier. With Tier 0 expanding the radius to 4, this becomes one of the largest AoE nukes in the game.

Budget Alternative: Any ice-damage card (★3)
Even a basic ice amp card benefits from Tier 2 double-dipping. Prioritize ice stats over generic crit cards.
Gem Setup
Weapon / Ring Gems (Type 1 — Offensive, 6 sockets total)
| Equipment | Socket 1 | Socket 2 | Socket 3 | Why |
|---|---|---|---|---|
| Weapon |  Cobalt (Ice) |
Cobalt (Ice) |
Cobalt (Ice) |
Tier 2 converts ice ATK → crit rate + crit DMG + skill DMG |
| Ring | Cobalt (Ice) |
Cobalt (Ice) |
 Ruby (ATK) |
1 Ruby for base ATK scaling on auto-attacks |
Armor / Amulet Gems (Type 2 — Defensive, 6 sockets total)
| Equipment | Socket 1 | Socket 2 | Socket 3 | Why |
|---|---|---|---|---|
| Armor |  Emerald (HP) |
Emerald (HP) |
 Diamond (All Resist) |
HP for survivability, Diamond for Abyss elements |
| Amulet | Emerald (HP) |
Emerald (HP) |
Diamond (All Resist) |
Extra resist coverage against non-ice elements |
Why 5 Cobalt + 1 Ruby instead of 6 Cobalt? Hakuya's auto-attacks still deal physical damage between skill casts. One Ruby ensures her autos contribute meaningful damage and help proc on-hit effects. However, if you have Silver Knight at high stars, 6 Cobalt is viable since card effects compensate for the lost ATK.
Key Insight: The Double-Dip
Most heroes need to split gems between damage stats and crit stats. Hakuya does not. Thanks to Tier 2 (Frost Crit):
| Cobalt Gem Gives | Standard Mage | Hakuya |
|---|---|---|
| Ice DMG | Yes | Yes |
| Crit Rate | No | Yes (25% of ice ATK) |
| Crit DMG | No | Yes (25% of ice ATK) |
| Skill DMG | No | Yes (25% of ice ATK) |
This means Hakuya gets roughly 4 stats from 1 gem type. No other hero in the game has this level of stat efficiency.
