Sea Twig(海枝枝)

Core damage skill. Base 60 energy cost, reduced to 57 when trait triggers. +10 power per 1 energy cost reduced. Combined with [Coral Bone] and [Sky Flood]'s energy cost reduction, can stack to extremely high power. Sea Branch's primary damage source.

Permanent -6 energy cost in counter status, stacked with [Coral Bone] can reduce high energy cost skills to minimal cost, while also providing extra power bonus for [Gushing Spring], forming positive feedback loop

Core buff skill. Massive +190% Magic Attack boost that enables devastating burst damage when paired with high-power skills. 0 energy cost allows flexible usage, making it key to initiating damage rotations.

Energy control and reaper method: 0 cost steals 3 enemy energy, disrupting opponent rhythm while creating conditions for "Backstab"; switching to "Backstab" when enemy energy is suppressed to 0 triggers 20x damage to complete the kill

Low-cost high-frequency damage. Only 20 Energy cost, 5-hit mechanism rapidly triggers multi-hit damage, extremely reliable when energy is tight or stable damage is needed, still decent damage with high Magic Attack base stats.

Core finisher skill. Deals 20x damage to enemies with 0 Energy. Combined with [Soul Snatch] or teammate Energy suppression, can instantly execute low-HP targets. Haizhizhi's most threatening execution method.

Energy control and tactical setup: 0 cost steals 3 energy, self-sustaining to relieve energy pressure while actively suppressing enemy energy to 0 to create conditions for "Backstab," also disrupting opponent's skill release rhythm

Boost start and counter switch. +90% Magic Attack boosts output base, if enemy switches this turn additionally gains +70% Speed, combined with Seabranch's 120 base speed can form speed suppression, punishing enemy switch behavior and triggering Coral Bone energy cost reduction.

Growth-type core damage skill: high initial 90 energy cost, but permanently +20 power at turn end. Grows stronger over time. Combined with [Coral Bone]'s energy cost reduction to lower casting cost, suitable for prolonged battles

Permanent -6 energy cost in counter status, stacked with [Coral Bone] can reduce [Water Wave] and [Gushing Spring] energy cost to extremely low, while itself is also high-power damage method, forming dual-core growth system

Massive buffing method. +190% Magic Attack provides the burst foundation for "Water Wave" and "Sky Flood," with 0 Energy cost for flexible use—key to activating growing damage output.

Sustain and energy cost management. 30 energy cost deals Magic damage and recovers 1 Energy, cost further reduced under energy cost reduction systems, can maintain skill cycle sustainability, avoiding empty energy deadlock.
