S-tier

A powerful card that Channels 1 Dark while immediately triggering every Dark Orb's passive (damage accumulation) on the spot. Upgraded, it triggers the passive twice, doubling the accumulation speed.

Dark Orbs grow each turn and, when Evoked, hit the lowest-HP enemy for the full stored damage. Using Darkness every turn to accelerate that storage dramatically increases the eventual Evoke burst. The standard Dark deck plan is to stack Dark Orbs big and release them all at once via Multi-Cast or Dual Cast. Higher Focus also scales the per-turn growth.

• Play every turn in a Dark deck to rapidly build up Dark Orb damage
• Upgraded doubles the accumulation per turn, bringing bosses into one-shot range faster
• After a few turns of stacking, release everything with Dual Cast or Multi-Cast to finish the boss
• Defragment increases Focus, further boosting the accumulation

• Dual Cast / Multi-Cast / Quadcast: Evokes pumped-up Dark Orbs multiple times for massive damage
• Defragment: Focus up also raises Darkness's accumulation
• Consume: Channels 2 Dark and Evokes the leftmost Orb at turn end. A Dark-focused Power card
• Shadow Shield: Block plus Dark Channel. Provides defense inside a Dark shell
• Null: Damage plus Weak plus Dark Channel. Serves as the attack card of a Dark deck
