Abyssal Gaze

passively her shot always splits into 2 / 3 / 4 arrows, with the extra ones weakened by 50% / 40% / 30%. The active part slows attack and movement speed of enemies in the area by 30%, and those who keep facing her for over 2 seconds are Petrified for 2 / 2.5 / 3 s, gaining 20% / 30% / 40% Physical Vulnerability, while petrified summons take extra damage equal to 30% / 40% / 50% of their current HP. Cooldown 25 / 20 / 15 s.

Role: a ranged Hunter with built-in crowd control — she stays in the back line, spreads damage across several targets and shuts down the enemy front with Petrify. Strong in the mid and late game, especially against summon-heavy boards, and she fills Marine and Hunter synergies.

Synergies

Marine · species
Synergy effect: (2) Magic resistance of all allied pieces +20%. (4) Magic resistance of all allied pieces +50%. (6) All allied Marine pieces gain the following effect: each time they take non-pure damage, they reflect pure damage equal to damage taken × their own magic resistance × 150%. Effects of several active thresholds stack together.
How to play
Marine is magic protection for the whole board: (2) already takes a noticeable bite out of enemy spellcasters, and (4) makes the team very resilient to magic damage. The thresholds are covered by heroes of different costs, so the core comes together in the mid game and the full build closer to the end. (6) turns defense into punishment: the higher the magic resistance, the more pure damage comes back to whoever hits the Marines.

Hunter · class
Synergy effect: (3) When an allied Hunter performs a basic attack, there is a 50% chance that it is a guaranteed hit and reduces the target's armor by 5 for 5 seconds. (6) When an allied Hunter performs a basic attack, there is an 80% chance that it is a guaranteed hit and reduces the target's armor by 8 for 10 seconds. (9) Basic attacks of allied Hunters knock the target back and launch an additional attack. Class trait: Hunters always prioritize attacking the enemy with the lowest health within their attack range. Knockback: forces the enemy to retreat to the cell opposite to its current facing direction; it can be dispelled. The effects of multiple tiers are active at the same time: activating a higher tier does not deactivate a lower one.
How to play
Hunters are a ranged physical damage class: from (3) their attacks often become guaranteed hits that strip the target's armor, and (6) makes this almost constant, so the enemy front loses its protection quickly. The class is wide and cheap: (3) comes together in the first rounds, (6) in the mid game, and (9) with knockback and extra attacks is a rare late-game option. Hunters need a sturdy front line in front of them, but thanks to their targeting trait they finish off the weakest enemies on their own.

Lore

hero story

I

The prey hid among the colored corals, thinking they could escape, until a sudden burst of arrows pierced the silence. The sharp arrowhead grazed their limb and ear. Trembling with fright, they scurried away in a panic and fled to the thick undersea forests. The hunter gracefully dropped her longbow which was studded with gems that matched her hair color, and followed closely after the prey. "Left or right?" She fingered her golden earrings and carelessly picked her hunting route. "Or..." She smiled and waved her hand, and a long hair behind her ear turned into a small colorful snake that wriggled across her neck and shoulders, flicking out its tongue. "Go, my cutie pie. Let's see how much prey we can catch." With a quiver full of arrows, she walked into the depths of the undersea forest contentedly.

II

"This is a prophecy from the ancient temple: Believers, the wrath of the abyss can be mollified only by offering your heart." "A few slaves are nothing compared to the safety of the city. Slaves are the most worthless in the ocean." "You pathetic slaves, once you have the honor to become the sacrifice for the power of abyss, you can make a contribution to the whole Marine." "Your soul will follow the power of abyss and turn into eternity, instead of being trapped in the squalid cramped slums. You have nothing to be scared of. Just enjoy the gift from God." Standing by the altar, Rusalka enjoyed the impassioned manifesto of the other slave-owners and gave a little chuckle from time to time. For the foolish inferiors, any rumour could easily become the truth. Fake piety and benevolence are just a joke before the maker of the prophecy. But she wanted to see how strong their "belief" was.

III

The runaway young slave stopped her. Before her guards drove him away, he fell down before her, crying bitterly. The ragged man sincerely complimented her on her beauty, tenderness and unrivaled power in a trembling voice. She knew that this was not simply because of her charm, but also because she could always provide the best shelter for her possessions. Through the eyes of her serpent hair she saw the slaves crying in front of the slave-owners' cudgels, being forced to toil and dying because of hunger and cold. She also witnessed this place grow into a prosperous city, with more deep-sea people living a stable life. It was said in the slums that her slaves could have eternal security. After all, whether nobles or slaves, she could easily see what they wanted. With the knack, she could control the whole city. All the prey would be brought to her.
