Battle Skill	Physical	Enemies take +% Physical DMG
Combo Skill	Arts (Originium)	Enemies take +% Arts DMG
Ultimate	Both	Large AoE with both debuffs

How Vulnerability Works

Stacks	Physical DMG Amp	Arts DMG Amp
1	+10%	+10%
2	+20%	+20%
3	+30%	+30%
Max	+50%	+50%

Talent: Blooming Vitality

• Passive team healing over time
• Triggers when Ardelia is on the field
• No SP cost - just stay in battle

Playstyle Guide

Core Loop

1. Battle Skill → Physical Vulnerability + Nature Infliction
2. Ally applies second element → Corrosion triggers
3. Combo Skill available → Arts Vulnerability
4. Ultimate when grouped → Both Vulnerabilities on all enemies
5. Swap to DPS → Massive amplified damage
6. Stay on field occasionally → Talent healing

Tips

• Don't ignore Battle Skill: Physical Vulnerability is powerful
• Time Ultimate for groups: AoE debuff is Ardelia's biggest value
• Rotate through Ardelia: Her Talent heals when she's active
• Pair with any team: She literally fits everywhere
