Overview
Mortefi is a 4★ Fusion Pistols Support from Huanglong and a featured 3.6 staple. He never left the premium cores because Lupa is limited and he is not. Field time is short: skill, shots, outro. Phase 2 rate-up is expected with Jingran.
Rotation
Healer outros. Mortefi intros, Resonance Skill, coordinated shots to bank Concerto, outro into the Heavy or Liberation carry. Do not on-field him as a Main DPS unless the floor is already dead.
Strengths
Defines A-tier teams through 3.6. Static Mist is a real weapon. Featured because 4-stars can define a team. Keep him capped.
Weaknesses
Lupa is a limited rival in the same chair. Wrong amp flavor for some Tune Strain cores. Easy to skip Sequences you already own copies toward.
Investment
Skill and Liberation. Waveplates on a coordinated set. Undying Flame until Static Mist drops.
Common Mistakes
On-fielding. Building Molten Rift as if he were Chixia. Leaving him at level 50. Four-person National Team copies.
