Calculations of attacks on enemies

Good morning E&P

I want to ask you a specific question, how are the attacks of each hero’s specials calculated? for example: if it says it causes 300% damage to the enemy ??? How much damage would the enemy receive ??? If you could clarify the doubt would be ideal to respond to my alliance! Greetings and thanks to everyone for the help !!!

Here is link to thread where it’s discussed in detail:
