Decay

Basic Info

• Type: Skill
• Cost: 1
• Effect: Apply 2 Frail. Apply 2 Weak. Exude.

Rating

A cost-1 double-debuff Skill that Exudes after use. Single-use, but packing Frail 2 + Weak 2 into one card is extremely efficient — Frail kills 25% of enemy attack, Weak kills another 25%. Enemy offense drops significantly.

Combined with Cursed Flesh Trick, the two debuff applications each proc bonus damage for 18-26 total — a cost-1 Exude that both defends and attacks hard. Weaken applied first doubles the effect of Frail and Weak, magnifying Decay further.

Rating: B-tier — Cursed Flesh Trick synergy makes this a surprisingly big damage card.

How to Use

• With Cursed Flesh Trick on, each debuff triggers 9-13 bonus damage — 18-26 total
• Cast Weaken first to double Frail and Weak effects
• Exude means one-and-done — duplicate with Harvest-style copy effects for multi-use
• Not a Doom setup, but Cursed Flesh Trick chain is very strong

Good Synergies

• Cursed Flesh Trick: +9-13 damage on each debuff. Decay's Frail + Weak = 18-26 bonus damage
• Weaken: doubles Weak/Frail effects for 3 turns. Cast before Decay for doubled debuffs
• Harvest: copy a card. Harvest Decay for multi-use
• No Escape: Doom-focused, not a pure debuff combo — but following Decay with No Escape keeps pressure on
