Rules and interpretation
Maximum rank and unlock level are read from the Survivors build. Damage and cooldown depend on rank, gear and runtime formulas; this entry does not substitute Diablo II values.
Evolution: reach rank 8, hold 
Vitality, reach hero level 12, then open a chest. This evolution is marked as keeping its source skill.
