Increasing spell's duration increment...

[Evil Dave]

I may be wrong, but it seems to me I've seen a feat or class feature
somewhere that will increase a spell's duration increment (rounds to
minutes, minutes to hours, etc.).

Can anyone point me to this if it exists, if not, oh well....

As far as I know there isn't.

When making magical items there is a cost progression:
Hours/Lv is base
10 mins/Lv = 1.5x base
Minutes/Lv = 2x base
Rounds/Lv = 4x base
Hours/Lv = 1/2 base

Okay, maybe this is what I was thinking of, have to run it past my current gm, but he does use a lot of third-party stuff, so maybe...

I think I would allow it... BUT with 1 modification:
Minutes becomes 10 minutes per caster lvl and 10 minutes per caster level becomes hours. It seems like the feat skipped that step making it too powerful imo.

There may have been in 3.5, but not Pathfinder.
