リージェント

• Type: Attack
• Cost: 0
• Effect: Spend 2 diamonds. Deal 14 damage to ALL enemies. Apply 2 Weak and 2 Vulnerable to ALL enemies.

Efficient AoE: 0 Energy + 2 diamonds for 14 AoE damage + 2 Weak + 2 Vulnerable to everyone. Not consuming Energy means it plugs in alongside other attacks and Skills seamlessly, and 2 diamonds is light enough to spread strong debuffs essentially for free.

Applying 2 Weak (-2 attack stack) and 2 Vulnerable (take more damage) simultaneously boosts your follow-up damage while softening enemy threat. With Genesis supplying 2-3 diamonds per turn, Meteor Shower becomes virtually free on every turn.

• Standard sequence: Apply debuffs early, then cash in via follow-up attacks
• 0 cost means play it on sight. Just secure the 2 diamonds and you're rarely stuck
• Multi-enemy fights scale 14 x enemy count — AoE efficiency is overwhelming

• Genesis: 2-3 diamonds per turn covers Meteor Shower's cost, making it effectively free every turn
• Heavenly Power: Meteor Shower applies 2 Vulnerable, then Heavenly Power's triple-hit cashes it in 3 times
• Seven Stars: With 2 Weak and 2 Vulnerable applied, Seven Stars' 7 AoE hits all benefit from the debuffs
• Comet: Meteor Shower applies Weak and Vulnerable; Comet then hits harder through the debuffed enemies
