Stigmata not visible

[CrazyClement]

I've been working on Wayne Houchin's Stigmata recently and it doesn't shows up on my arm clearly...what should I do? I've already been experimenting and it is still very faint...it only shows up bright red after two minutes or more...how should I solve this?

Thanks

I'd stay away from the real time predictions then. It can work just fine if you prep early and force something so that by the time you need to reveal it is fairly bright.
