It came up in the lobby today that if Blessed is in play you can not use the Sparkler to undim a non-geek creature. What say ye? I'd say that it should be possible personally. And what about Energy? Should that work on non-geeks??

we also have to see if manipulation works...

Abrizian Sparked work, energy won't actually help, because it undims after dimming, but if creature always dimmed energy won't help.
According to Blessed are the Meek decription "don't undim as normal" is almost same as "don't undim at start of every round". I used 'almost' because some creatures will undim (for example Naga Sentineil description: "Doesn't undim as normal").

Now all cases should be clear.

EDIT: just checked code: no, I was wrong, looks like nothing can undim creature. It will be fixed.

what a quick response to a possible bug... thank you
