Water Bottle

A consumable that heals 5 HP and grants Heatwave immunity. Unlike most single-use heals, it refills automatically when the wearer is hit by water element effects, making it reusable in the right environment. Keep it on a cat moving through water-element areas or against water-using enemies for persistent healing and reliable Heatwave protection.

The self-refilling mechanic is Water Bottle's standout feature. Most consumables are exhausted after a single use, but being hit by water element effects restores Water Bottle to full, allowing the 5 HP heal and Heatwave immunity to be used again. In chapters or encounters with water-using enemies, this effectively turns Water Bottle into a renewable healing source. Heatwave immunity is situationally valuable for specific maps or weather conditions that apply Heatwave to your team.

Water Bottle is most powerful when paired with deliberately sought water-element encounters where the refill triggers frequently. Assign it to a cat that can absorb water hits without consequence — perhaps one with water resistance — and they'll benefit from recurring heals throughout the fight. Outside water-heavy encounters, it still provides a free 5 HP heal plus Heatwave protection, which is worth the slot on any cat heading into a Heatwave-affected area. Low-maintenance but surprisingly durable across the right run segments.
