Upgraded

• Cost: 1
• Effect: Weak enemies take 50% additional damage.

A Cost 1 permanent Power granting +25% damage (+50% upgraded) to Weak enemies. The core of Weak decks — apply Weak and every Attack carries a 25-50% damage bonus forever. Upgraded 50% is extremely powerful — a 30-damage Attack becomes 45. In Weak decks, Ruthlessness establishes a "apply Weak → all Attacks x1.5" pattern. Combined with Weak appliers (Bash, Uppercut, Tremor, Provoke), combat-wide damage efficiency dramatically improves.

Early combat, deploy alongside Weak application so all Attacks carry +25-50% damage going forward. Bash (Weak + Vulnerable) → Ruthlessness delivers multiplied damage via both debuffs. Tremor (Cost 0, Weak 3) → Ruthlessness locks in Ruthlessness's bonus on all subsequent Weak turns. When Ruthlessness lands early in Weak decks, damage stays at 1.25-1.5x throughout the fight — effective in both short and long battles. Whirlwind (X AoE) or Skull Bash (high single-target) carrying Ruthlessness's 1.5x delivers enormous damage.

• Bash: Weak + Vulnerable attack. With Ruthlessness, forms the Weak deck's base combo, dramatically boosting damage efficiency.
• Tremor: Cost 0 Weak 3-stack skill. Paired with Ruthlessness, instantly activates the full bonus at 0 cost.
• Giant: 50% damage cut from Weak enemies skill. Ruthlessness amps offense while Giant secures defense — the Weak synergy's complete form.
• Whirlwind: X-cost AoE. Ruthlessness's 1.5x rides on each Weak enemy, exploding board damage.
• Dismantle: Attack hitting twice against Weak enemies. Ruthlessness bonus rides both hits for exceptional efficiency.
