Trevasso

Increases the damage dealt by dark-attribute cards. For builds that stack dark-type cards, this relic adds a flat damage amplifier on top of the existing combo multiplier, resulting in substantially higher per-card damage output against all enemy types.

Found in the Dark Corridor area, a late-game region. If you're committing to a dark-attribute build, actively route toward this area.

A high-value relic specifically for dark-attribute builds. When paired with the combo multiplier from Combo Stack, dark cards can reach disproportionately high damage numbers — particularly against late-game high-HP bosses. Outside of dark-focused builds, the relic provides no benefit, so committing to the dark archetype before picking this up is essential.

• Build your deck with a majority of dark-attribute cards to fully capitalize on the damage amplification
• The synergy with Combo Stack is multiplicative in effect: dark cards hit harder, and a long combo chain multiplies those harder hits
• If Arcana passives exist that further enhance dark damage, stacking them with Darkasso creates overwhelming burst damage potential against bosses
• Pairs with Overkill: amplified dark damage produces larger overkill numbers, converting into more coins per kill
• Maintain proper mana cost ascending order even in dark-heavy decks — the combo chain must stay intact for the amplifier to matter
