Catch % Rate Options

[Armanic]

General idea:
I want to create an event where a little boy asks you to catch the squirrels he lost, there are 10 of them in total.
I created a false item named "Squirrel" and found how to make it so the little boy can count them so you don't end the quest with only 1 Squirrel instead of 10.

Now my current problem is; How to make it so Squirrels are not caught 100% of the time? I'd like something like 55% catch rate.

Thanks!

Well we have a small thread located in the Gameplay forums for you to post WIP games that don't quite hit the criterea for the Submission. So what I'd suggest you do. Is to post it in the Project Hype and Advertisment thread which is pinned in the Design Critique forums. You can create an entire post in here without screenshots if you so wish. And people can come a view it. When it comes to a time when you feel your thread will follow the rules you either Report your posts or PM one of the mods of the Gameplay Section and we'll move it over for you.
