버블코타

Each basic attack triggers the [Gacha] once, randomly firing an orange, purple, blue, or gold bubble and adding that bubble color to the gacha slots. Gold bubbles have a 1% chance to appear, while each other color has a 33% chance to appear. When the slots hold 5 bubbles of the same color, or when a gold bubble appears, all bubbles are cleared and [Jackpot] begins for 10s. While [Jackpot] is active, basic attacks no longer trigger the gacha, and basic attack damage increases by 80%.
