Combat Mechanics
Aventurine excels as both a sustain and damage-dealing unit, with a kit that rewards strategic planning:
- Basic Attack – Straight Bet: Single-target Imaginary DMG scaling with DEF (50–110%).
- Skill – Cornerstone Deluxe: Grants Fortified Wager shields to allies (16–25.6% of DEF + 80–356), stacking up to 200% and lasting three turns. Shields bolster survivability and synergize with Follow-up attack teams.
- Ultimate – Roulette Shark: Randomly gains 1–7 Blind Bet points, inflicts Unnerved on a target, and deals high Imaginary DMG (162–291.6% of DEF). Allies attacking Unnerved targets gain increased CRIT DMG.
- Talent – Shot Loaded Right: Enhances Effect RES for shielded allies, accumulates Blind Bet points when attacked, and triggers a 7-hit Follow-up attack when Blind Bet reaches 7.
- Technique – The Red or the Black: Provides variable DEF boosts (24–60%) and applies the highest DEF buff to allies at the start of the next battle.
Aventurine’s power scales with DEF, making him both a tanky support and a potent damage dealer when built correctly.
