Pure Water

Pure Water is the Watcher's starting relic, equipped from the beginning of every run. At the start of each combat, it adds a Miracle card to your hand. Miracle is a 0-cost card that generates 1 Energy when played, effectively giving the Watcher a free extra energy on turn 1 every combat if you choose to use it.

Even a single free Miracle can open up plays that would otherwise require waiting a turn, particularly when combined with the Watcher's stance-switching mechanics. The extra energy on turn 1 is especially potent because it accelerates the Watcher's ability to enter Divinity stance, which triples all damage. Pure Water is a fairly understated relic compared to other starters, but the consistent tempo boost it provides is meaningful across a long run. It is replaced by Holy Water upon defeating the first boss, which provides 3 Miracles at the start of each combat instead of 1.
