Glowing Black Shard

The fully charged form of the Black Shard, achieved after absorbing 20 low-HP enemies. Deals 5 damage with Lifesteal, inflicts Burn 5, and purges all buffs from the target. Crucially, it instantly kills The Coven boss — and doing so activates the Obelisk in the Core, advancing the main questline. Part of the Obelisk set.
