Black Shard

A quest weapon that grows more powerful by absorbing weakened enemies. Absorb any unit at 1 or less HP to charge it up — after 20 absorptions it transforms into the Glowing Black Shard. The Black Shard ignores shields and cannot be blocked, and its damage scales with accumulated Charge. Power persists across runs, so the 20 kills need not be completed in a single adventure. Obtained by defeating Zaratana. Part of the Obelisk set.

Ignoring shields and being unblockable means the Black Shard bypasses two of the most common defensive mechanisms in Mewgenics — enemies with stacked Shield or block passives take full damage regardless. The Charge-scaling damage means the weapon grows stronger as absorptions accumulate, rewarding patient play that brings enemies to 1 HP before finishing them. At 1 or more Charge it is already a decent weapon; at near-20 Charge before transformation it can become formidable.

The cross-run persistence means every run that uses the Black Shard contributes to its ultimate form. Prioritize absorbing the cheapest and most common enemies to rack up absorptions efficiently rather than saving the ability for bosses. Items or abilities that can quickly chip enemies to exactly 1 HP pair perfectly with the Black Shard, setting up absorptions without wasting attack turns. Once it transforms into the Glowing Black Shard, keep it equipped for The Coven encounter.
