Hypercharge last for 20 seconds, its a buff on your current turret, and every attack of your turret will apply a Physical (Rook) or Magical (Bishop) vulnerability for 10 seconds on the target refreshing the effect with every attack (Bishop turret does AoE attacks and apply the debuff to multiple targets), making this debuff duration around 29 or 30 seconds.
yeah just learned about that through a friend but still i believe foe last longer and more powerful with BV so it works better with magic comps.
