Hidden Maps

Are hidden maps obtainable from ANY map?

I have seen people saying Boardskin and Pestiskin but what about Toadskin, Goatskin, Leather?

I've gotten two from toadskin maps.

Thanks for fast reply :)

Got from boarskin, can't imagine goat or leather will have it since their lower level and the hidden map is 50

I have run 12 unhidden maps so far. I have attained them from Leather, Goat, Toad and Boar. I have run five unique bosses so far and I'm not sure if more exist. The treasure chest fight has paid the best so far with 50,000 gil and a ton of loot! No minion yet...

Yeah I had the mimic chest one, yielded so many drops, polar lens the lot

Does anyone got them from Peisteskin Maps? Because the patch-note say so.

Yeah, two of my LS mates got it from a Peist.

Found 3 so far. Only rare mat was polarized glass each time.

Roughly what's the ratio to find a hidden map? I've been running with some friends and we haven't seen even 1 yet across peiste, boar, and toadskin types.
