Div card drop level rules?

I want to farm Mitts div card in SSF for Hrimsorrow. It is a very common card and a very common unique, but if I get unlucky and need to farm the Mitts div card I want to find where in the campaign it will drop. I see at https://poedb.tw/us/Mitts that it drops in a number of zones. Two of them in the campaign which is great. But I'm afraid if I outlevel these places div cards stop dropping. What level do they stop dropping? If The Ascent is a monster level 40 zone, what level is "too high?" 45? 50?

Thank you.

See the wiki entry here re drop rate penalties:

Yeah if you out level a zone you'll get much much less drops of divination cards. I would suggest finding a zone in maps where it drops to farm higher the zone less reduction in drops you'll get for being over leveled. However you will probably need to farm way to many of those card sets if your looking for one specific unique I would suggest instead possibly trying to just farm stacked decks you'll get a lot more value and still have a decent chance at those gloves. Stacked decks are also a lot easier to target farm.

Oh also I just though you could load up on magic find and just farm a low level zone for them to because they are common low level uniques. People used to do this to farm tabula and gold rims it'll be a pain but about as much of a pain as trying to get them from div cards.

Mitts is a somewhat common reward in TOTA rank 150+. A little late to help you if you don't already have Silver Coins farmed but I got a bunch of Mitts cards from the TOTA system. I've seen it pop up as a reward at least six times so far.
