Cristallo Build Breakdown: Mineral Afflatus DEF Shred & Buffs

Cristallo stands out as a 4-star Mineral Afflatus support in Reverse: 1999, excelling in team sustain through powerful Sturdiness buffs and debilitating Nasty Wound debuffs. Her abilities provide mass damage reduction for allies, shred enemy Reality DEF by up to 25%, and apply Genesis DoT while crippling enemy healing by 15-50% depending on stacks. 

This makes her a low-investment powerhouse for Reality damage teams, particularly effective against Beast enemies due to Mineral's Afflatus advantage in the cycle (Beast weak to Mineral). As a story-obtainable unit, she requires minimal resources to shine in early PvE, Limbo, and content requiring prolonged fights.​​

Detailed Skills Breakdown

Cristallo's kit revolves around proactive buffing and reactive debuffing for superior team control:

Caged Bird (Basic Attack): Deals single-target Reality DMG and applies a 25% Reality DEF Down debuff for 2 rounds at Lv.6+, stacking with team sources for massive DPS amplification on bosses or elites. Use this to soften high-priority targets before ally bursts.​

Dustless Blossom (Skill 1): Grants all allies 1 stack of Sturdiness (25% DMG Taken Reduction per stack on hit, consumes 1 stack) and +20% Reality/Mental DEF for 2 rounds at max level. This is her core skill—prioritize Lv.2+ for 2 stacks initially, enabling teams to tank heavy hits while building stacks over rounds.​​

Radiation Therapy (Ultimate): AoE applies Nasty Wound (15% Healing Taken Down + 15% DMG Taken Reduction Down per stack, up to 3 stacks for 50% total) plus round-end Genesis DMG scaling with her ATK. Perfect for wave clear or denying enemy healers, synergizing with DoT carries for sustained pressure.​

Level all skills evenly to Insight I for bonus DEF/healing on buffs; her scaling favors ATK investment for DoT/healing potency without sacrificing support.​

Optimal Psychubes & Stats Priority

Psychubes should enhance Cristallo's ATK for DoT/healing, extend debuffs, or reduce cooldowns for constant uptime:

Stat Priority: ATK > Reality DMG% > Speed > HP/DEF. Aim for 2500+ ATK at Lv.60 for optimal scaling; Resonances to R7+ add survival via dodge/evasion.​​

Advanced Team Compositions

Cristallo anchors Reality-heavy comps, leveraging DEF shred for carries and Sturdiness for immortality:

Pure Reality Sustain: Cristallo (debuff/shield) + Ms. Newbabel (shields scale with Reality DEF) + Leilani (Reality DPS burst). Shred enables Newbabel's shields to hit 50k+ while Sturdiness tanks.​

Hybrid DoT Control: Cristallo + Balloon Party (heal/DEF) + Sotheby (Mental DoT) + Mineral DPS. Nasty Wound neuters enemy recovery; strong vs. Beast waves.​​

F2P Budget: Cristallo + APPLe (hybrid heal/DPS) + Centurion (tank/control). Covers sustain, damage, and Afflatus advantages universally.​

Playstyle & Investment Tips

Rotation: Open Dustless Blossom for stacks > Caged Bird on bosses > Ultimate on clumps/healers. Maintain 2+ Sturdiness stacks by avoiding overkill.

Matchups: Dominates Beast (e.g., early chapters); pair with Plant/Star for full cycle coverage.​

Investment Path: Skills to 8/8/8 > Insight I > R6-R9 Resonances > Duplicate for Portray II (extra stacks). Total cost: ~200k Sharp Solvent, viable F2P.​​

Counters: Avoid pure Physical teams; her Mineral weakness to Star means shielding priority.

Cristallo redefines budget support with unmatched utility, turning fragile Reality squads into unkillable machines through layered buffs and debuffs.​​
