HSR 4.3 New Character
Mortenax Blade
Mortenax Blade enters the meta as a 5★ Fire Nihility Hybrid Carry. He operates as a destructive centerpiece who completely warps traditional team building by converting personal HP-consumption into massive AoE follow-up damage and unmatched defensive shredding. As a premier engine for modern debuff/coordinated-attack architectures, he handles debuffing, personal sub-DPS execution, and hypercarry amplification simultaneously within a single slot. His full kit brings an aggressive multi-DPS synergy to the roster, making him a must-watch anchor for high-end account optimization.
