Drench
The tide rises and turns one of your runes to Water. If that rune was alight, the water puts it out. Frozen, cursed and healing blocks are left where they are.
In detail
Driftwood Totem's proc on a Water match. It turns one random eligible block into a Water rune. Ordinary and ignited blocks qualify, and converting an ignited block puts it out at no cost; frozen, cursed, wrapped, petrified, healing and existing Water cells are skipped. It seeds more Water for easy combos and is self-limiting, since Water matches consume Water and it only fires on a Water match.
