Hey Com,
im new into the ue4 and i have an important question.
I´d like to create a game where the character can get skills like fire. Then when he activates his power skill, his cant be hit anymore and disappear like on this screen from one piece burning blood:

The other extra then i want to do is the following… While the skill is activated (im thinking off about 4 seconds) the character should have fire on his body. Like this scrren here:
How do i get this as the best way?
Also there is the problem that the character should just be able to use this “skill” if he has collected the item. Is there any problem? Would great if someone could help me 
Greetings
