Honkai: Star Rail’s upcoming 3.2 update is set to introduce Castorice, and her leaked traces suggest she could be a game-changing unit. Below, we break down each of her traces, explaining how they function and what they mean for her playstyle.

Castorice’s Traces Breakdown

Trace 1 – Speed Boost Based on HP Threshold

• When Castorice or her Memo Sprite has HP above a certain threshold, a Speed increase is applied.
• The specific unit benefiting from the Speed boost is unclear, but Pollock is a likely candidate due to his naturally higher speed.

Trace 2 – Excess Healing Conversion

This trace modifies how excess healing (healing that goes beyond max HP) is utilized:

• If Memo Sprite is NOT on the field → Excess healing restores special energy.
• If Memo Sprite is on the field → Excess healing on other units heals Memo Sprite’s HP.

Trace 3 – HP Scaling to Crit DMG

• If Castorice’s Max HP exceeds a certain threshold, she gains Crit DMG for every specific point exceeded.
• The upper limit of this effect is currently unknown, suggesting Castorice can be fully built around HP for maximum damage.
• However, since none of her traces provide Crit Rate, she may require 100% Crit Rate from gear and external sources.

What This Means for Castorice’s Build

• She is likely an HP-scaling unit, meaning investing heavily in HP% artifacts and relics will increase her Crit DMG.
• Excess healing mechanics may make her synergize well with sustain units that generate surplus healing.
• Depending on her base stats, she could require external Crit Rate sources (such as sub-stats, Light Cones, or team buffs).

Final Thoughts

With her beta testing starting soon, we will soon get a firsthand look at how Castorice’s traces translate into real gameplay. If her kit lives up to expectations, she could become a powerful HP-scaling DPS or hybrid support in Honkai: Star Rail.
