Quick answer: In the Clock Tower’s Path of the Builder, a chest midway down the hall, between two gates, contains the Moonlit Shard relic. Foundry Apex is the nearest Mirror of Life, and kills grant Rose 20% extra XP when she is at full life.
Where the Moonlit Shard is
The relic is in the Clock Tower, in a district called the Path of the Builder. That hall is lined with iron fist traps and crushing pistons. Partway through it, a small chamber sits between two gates. The chest inside is dark with gold trim, and orange furnace light glows behind it.

What the Moonlit Shard does
The MOONLIT SHARD is a relic. Its card reads:
“Rose gains 20% more XP by killing enemies as long as she has 100% of her maximum life.”
The flavour text adds: “Once worn by ladies of the court, this refined jewel held both hairstyles and secrets in place.”

To equip it, use Hold to equip on the card when it appears. You can also equip it later from the Equipment screen.
The bonus switches off as soon as Rose takes a hit and drops below full life.
That makes the Moonlit Shard a fit for careful play and for grinding levels, such as XP farming with the Phantom Ring. To compare it with other relics, check how the relics rank.
