Upgraded

• Cost: 1
• Effect: Osty deals 9 damage. Deal additional damage equal to Osty's current HP.

A unique Attack that converts Osty's current HP into damage. The higher Osty's HP, the bigger the hit — Osty HP management becomes the main strategic lever.

With Osty at near-max (typically 10-20 HP), cost 1 delivers base 6 + HP damage — a very high damage-per-energy rate. Keeping Osty topped up with Encouragement pays off massively. Upgraded bumps the base to 9, making the overall rate even better.

Rating: A-tier — huge damage whenever Osty's HP is managed well.

• Play when Osty HP is high for maximum damage
• Pre-heal Osty with Encouragement for a burst turn
• Save your Osty HP stockpile for boss / elite timing
• With Necromastery, Osty HP loss also hits all enemies — doubled value

• Encouragement: Osty +5 HP + Revive 3. Max out Osty the turn before Unleash
• Necromastery: Osty HP loss = AoE damage. Unleash's base damage can also AoE via it
• Bone Reinforcement: Osty +4 damage — boosts Unleash's fixed portion
• Revive: Revive 25 keeps Osty topped up for full-power Unleashes
