I read a topic about making a poison skill and I was wondering how would you make a poison skills that could stack? So if you activated it on some one 5 times and it does 3dps each it would then do 15dps.


Also how would I make a skill that would make me invis for like 3 sec then visible and have a puff of smoke when going vis/invis? But my guns would be visible when I am invis?


Lastly how would I, as and ability\ulti, make an explosion(like unded) at my view co-ords?
