This is something that I find crappy because by default if you get hit you'll get poisoned unless your fortunate enough on having higher strengths over it.
I prefer it as a chance and so I was going to do it via an event.
Now the problem is how can I know which will be the target? The rest of the event is fairly easy you just need to make a random variable and a conditional to your specific percentage then inflict the status effect if it succeeds.
Anyone know what could I do?
