SQL

After casting Resonance Skill - Deadlock, Lucy enters Algorithm Compaction and gains 1 {Cus:Sap,S=stack P=stacks SapTag=0} of SQL.
While in Algorithm Compaction, casting Resonance Skill - Deadlock will not grant SQL again.
When casting Heavy Attack - Multi-threading, if Lucy has SQL, increase this attack's DMG Multiplier by 270% and remove SQL.
When casting Heavy Attack - Multi-threading, if Lucy does not have SQL, she loses 20% of current HP. If Lucy's HP is below 1%, no HP is consumed.
