Layla has a basic attack damage of 47 and she attacks once every 2 seconds, it travels the fastest amongst all of her attacks. Once Layla has started her attack, she immediately and simultaneously also lets out a plasma beam dealing 200% of her basic attack damage. Her plasma beam overheats and can fire again automatically every 5 seconds. The excess energy coming the plasma beams charges Layla's super laser cannon. It takes 5 plasma beam attack to fully charge the super laser cannon which deals 1380 damage, however, when using the super laser cannon, Layla needs to halt all her other attacks, take 5 seconds of her time to set up and fire the super laser cannon. Layla can resume doing all her attacks 3 seconds after she fires her super laser cannon. Note, Layla hates Tigrel so much that she fires all of her attacks everytime it is ready. HOW LONG IN SECONDS will it take Layla to take down Tigrel by bringing Tigrel's health points (HP) to zero given that Tigrel has 7300 max HP which regenerates by 132 once every 8 seconds when HP is not full. Tigrel's shield also automatically blocks or reduces all incoming damage to zero on every 5th time he is about to receive a damage
