[Tiche3]

Hi guys, wanted to write here becouse i need help (badly ;/)

I want to make a spell that sounds something like this:

With each attack, Blezz has a chance to duplicate himself (PASSIVE):
Level 1- 5% chance, illusions deal 25% damage, gets 600%
Level 2- 10% chance, illiusions deal 35% damage, gets 500%
Level 3- 15% chacne, illiusions deal 45% damage, gets 400%
Level 4- 20% chance, illiusions deal 55% damage, gets 300%

If anyone could help me do this spell (a testmap or w/e)
It would be greatfull (oh yeah gui ofcourse plox)

Tich3 i would help you but you seem very new to THWS same as me but i see people like this as freeloaders. And since this is a dota spell why not search for it.
Edit:
I thought i might help you out quickly =)
Sorry for the above and heres the spell
Edit 2:
No need to give credit and im sure there are better ways to make the spell but this is mine ok
